    Are they building their new nuclear reactors with 50 year old technology on fault lines next to an ocean with an insufficient battery back up? That would be the only reason a sensible person would look at the Fukushima and decide not to build a nuclear power plant.

    Probably close to all 3 of the above actually.

    Seriously.

    That fault line isn't a valid building location? No problem sir, how much to 'move the fault line' on that map? Done and done. China has a big coast, that's most of their economic activity, and if not a coast, a major river (which faces essentially the same weird random shit happening problem). Things like safe materials and locations aren't high priorities when you can bribe your way to safety.

    And 50 year old technology. Well are you going to sell them brand new technology? How new is our technology? For quite a while we weren't doing anything dramatically different with reactor designs in the west. So... maybe not a 50 year old design, but a design that is basically 40 years old? That wouldn't surprise me in the slightest.

    There are lessons every reactor can learn from fukushima about, as you say, battery backups and various types of alternate power arrangements and so on. But their 'generation II' reactors in many cases are technology from the 50's through the 70's give or take some minor updating but the core reactor tech didn't change much. Fukushima Daiichi used boiling water reactors which, from the article, are generation 2 reactors. Which is what the chinese are phasing out.

    Reactor technology didn't radically change much in the last 40 years, or even a bit longer than that. At least not in the core mode of operation (boiling water, gas cooled, pressurized water etc.). Add to that the fact that the chinese are probably doing a shitty job of actually building the reactors in some cases (where the japanese built it the way it was intended, the design just wasn't up to the disaster, would you want to have trusted chinese concrete with that problem too?) and you're begging for trouble. A lot of it.

    If you read up on the AP1000... while I'd be confident of westinghouse building them properly in the US, there's a LOT that can go wrong with that design if people try and cut corners. If I were the chinese government I'd be thinking they aren't really the best plan given corruption. Lopping off the head of a corrupt official doesn't put 100 000 people back in their homes.

    Erm... no one talks about it because it exists. You don't have to use your own currency. You can do business in any foreign currency and then convert to dollars for tax purposes, and you can barter. You just still have to pay tax on the equivalent to your own currency. Lots of countries peg their currencies to someone else's for just that reason, it's a free market as to which currency you pick.

    The problem with fiat money is that it can be created at no cost. That is the ultimate power and will always be abused.

    How often has it actually been abused and how often has it been used to positive effect? Germany Japan and Canada are where we are because we've devalued currencies relative to the dollar by conjuring money out of thin air essentially, keeping our exports competitive. The rising cost of the canadian dollar (due to oil) for example has eviscerated the manufacturing sector who are now 30% or so more expensive to hire than they were 15 years ago. If we had a government that cared about manufacturing and the hundreds of thousands of jobs that come with that and the 16 billion dollar deficit ontario runs because of the manufacturing crash the federal government would have kept devaluing the dollar to keep it at probably 60 or 70 cents US.

    Hyperinflation in most cases is actually symptomatic of a different problem, rather than a cause of it. The Weimar republic, zimbabwe, argentina the free city of Danzig, the US in the independence revolt, the both sides in the civil war etc. all had serious inflation problems because their economies were being wrecked by various other factors (wars, debt in foreign currency, coups, sanctions etc.), and in those cases weird shit happens. Weird shit happens with gold too, because if you couldn't get gold due to sanctions for trade you're basically trapped in a massive economic death spiral.

    Small devaluation to positive effect is much harder to spit out a list of. It doesn't make huge sexy numbers that are entertaining (like having a quadrillion dollar note being really equal to one dollar), when you devalue your currency by 5% which keeps your exports competitive no one writes a giant wikipedia article on it.

Attracting investment/tourism/making exports better are all good things as that creates jobs and helps people get out of debt. An uncompetitive economy has a very hard time internally devaluing (imagine everyone taking a 2% pay cut a year).

    As I said to someone else, it's a mostly american concept that devaluing a currency could ever be bad. Germany Japan Canada all have used currency devaluation quite successfully to bolster their economies.

    Also, whatever you may think of government debt, it's there, the country can't just absolve itself of paying it, so it has to be paid off somehow. If you're a greek, on a personal basis, the best thing to do is to leave greece because otherwise you're going to be paying 20% of your taxes into interest on debt incurred before you could even pay tax. That debt has to be whittled down, and the only ways to do that are increased tax revenue (which directly takes money out of peoples hands), or inflation which effectively reduces the value of the debt. Cutting spending shrinks the economy and makes the debt proportionally worse (so long as there's high unemployment, which there is, if there's low unemployment cutting the size of government provides more labour for the private sector to take advantage of).

    You have to be careful, because you suggested something thats true, but only in a narrow range.

    The people should be completely fucked over for the value of their saved money

    The important part here is that you're supposing that's a lot of people. If someone has net debt (including their liabilities through government) then devaluing the debt is good for them. If they can keep wage growth on part with, or faster than their interest rates, their debt will shrink proportionally to their earnings and make them net wealth holders sooner. If they have *any* debt at all devaluing debt through inflation is helps them with part of their balance sheet, whether their 'cash on hand' can keep appropriate pace is trickier.

    Funny how it works that the rich and bankers are the ones that end up getting the money because it is in "the people's best interest".

    You can't have it both ways. Either it's bad for people who have money (the rich, who's cash holdings are devalued) or it's good for the rich (who's are getting interest on the debt) it can't be both, though it can be neutral. So which is your argument? Inflation will reduce their wealth slowly, because as you say, it devalued holding denominated in that currency. So yes, if you have 4% inflation and they have 3% salary growth they appear to be making a lot of money, but their relative position to the overall economy would be retreating.

    Also, deflation is far more problematic than inflation, so you don't want that. Small inflation is always preferable to deflation, (and it's very hard to hit a 0 inflation target intentionally), and more inflation has advantages in getting out of debt.

The database logs no transactions, once a transaction is complete it is done and irreversibly one way, and randomly changes your unique ID after each transaction. No logging would make it fully anonymous (just like cash!), but everyone would have to explicitly trust the issuing authority (whomever controls the database) to responsibly manage it (just like the government!). If you mean a cryptographically untracably anonymous system I don't think that's realistically possible with todays maths. Every exchange that can happen *can* be logged, and since it requires unique identifiers it's possible to log the transactions and work backwords so to speak.

If it weren't for that the UK could theoretically still be buried with 200 or 300% of GDP in debt in gold that it could never pay back from WW2, leaving it a shell of a country.

    Devaluing the currency removes the incentive to save, and forces people to 'invest'

    Yep, that's probably the most profoundly useful thing about fiat currency. Gold sitting in a vault isn't flowing into the economy. Investing, even into boring government debt at least keeps the money moving around. Admittedly I probably should have clarified that I was talking about a crude approximation on the velocity factor in economic theory. It makes a huge difference. Sitting on money in a vault is pretty much the most useless thing you can do with it, and deprives everyone else of access to it, contracting the economy as a whole.

    If gold was still used by everyone as money, politicians couldn't promise things they can't afford, and bankers couldn't endlessly inflate the money supply, forcing everyone to 'invest' with them.

    Right. That's the situation Greece is in. They don't control the supply of euro's any more than they would control the supply of gold. They have 160 or so percent of GDP in debt, can't get investment (euro's or gold) so they need to devalue, which, when you have euro's and gold basically spirals the country deeper into debt that it can't pay off. If they could print more money, say an inflation target of 4% they would be devaluing greek labour relative to say germany, which would fairly quickly make greece a good investment opportunity for business (decreasing relative labour costs), a cheaper vacation spot as time goes on etc. And all that debt they had would start to chip away. They'd still be 10 years getting to 100% of GDP in debt, but as it is in 10 years greece is going to have 170 or 180% of GDP, if not more (unless they go bankrupt obviously) in debt, a population that's fleeing and they're going to face a complete economic disaster. In that sense the Euro and Gold are no different. Note that I'm explicitly not saying the US dollar is the same way, since the US has a federal system that doesn't cut health spending or pensions in florida just because there was a housing crash in florida. By that reasoning another option for the Euro is a more federal state where certain things (pensions, healthcare, justice, education, state ownership of pan euro corporations, such as the bank bailouts, would be trans Eurozone).

There are, if you are inclined to look for it, statistics for the countries (such as france) that reduced the limit from 0.08 to 0.05.

    So then what's the risk that you want? Up to 0.04 there's virtually no meaningful or measurable risk. After that you start seeing a decrease in driving performance.

    Also japan has the same thing you suggest. Impairment is impairment, they don't care if you're tired, high, drunk etc.. It's all impaired.

    The reason you can't just rely on personal judgment is that people are bad at judging their own drunkenness, and the government doesn't want you to be recklessly on the road. It's much easier for everyone if they set a limit based on (quite well defined) averages about how people perform than let you judge for yourself and hope you don't cause an accident.

    Just because performance drops off after 0.04 doesn't mean that's where the limit should be.

    I posted above or below or something, with a couple of more sophisticated links. To 0.04 it's basically impossible to tell that there's a performance dropoff. After that point there is a dropoff, but 0.05 (which is the legal limit in most of the world) is not much different. But that's a much more sophisticated risk analysis. The data is pretty clear, there's almost no risk up to 0.04, beyond that, your mileage may vary.

    Which figure?

    Figure 2 (top left corner) is 'equivalent to drink', if you get tired enough you stop behaving like a drunk.

    Figure 1b is where the real money is. And it's quite clearly a downward trend after 1.04. There appears to be one outlying data point at 0.1. And I would say that highlights what's wrong with their data at all (admittedly, it's not the focus of the paper but still) they should have error bars on their data points, or the table sample size.

    The second link actually agrees with the first more or less, but it's harder to read.

    Just looking at the data there is no situation where the 0.10 and 0.12 outperform the 0.04, even including the one wacky data point.

    The first links actual research is figure 2, so they have error bars correctly there, but that's 'equivalent to the effect of drink' not 'effect of drink' which is figure 1b.
