    So you want a metal detector and at least one security officer stationed at every entrance of every building in the country? Why not just provide all adult citizens with basic armed and unarmed combat training, and ensure that all have access to a weapon? When Charles Whitman was shooting from the University of Texas belltower, citizens helped the police, deputies and Rangers by bringing their own firearms and trying to pick him off. If just a few--maybe just one--person in the building had had training, he might have been able to stop the shooter. If just one had had a gun, he might have been able to kill the shooter.

    Less guns doesn't work--there are still other weapons. Banning all weapons makes us into the UK, where it's illegal to defend yourself with a stick!

    Ummm, that's exactly what Virginia Tech tried to do. It forbade all students to carry weapons, and then when one broke the rules, the rest were like sheep led unto the slaughter. Weapons bans are not obeyed by criminals; that's part of what makes them criminals.

    Arming private citizens is the only way to effectively limit the damage caused in these situations. We can't keep weapons out of the hands of criminals--our experience in Washington, DC has shown that (so have the British & Australian experiences)--so we must have more weapons in the hands of trained, law-abiding citizens. The police can't protect us; all they can do is mop up the blood and draw chalk outlines afterwards.

    Actually, most folks who carry concealed say that after a few times you start to regard it as a duty to be armed, simply in order to stop incidents like this. Yeah, they're few and far between, but they can be stopped.

    We have three alternatives: ban weapons (it never stops at guns--eventually it trickles down to knives, swords, bats and so forth) for everyone except the police & military; allow weapons to those who want them; mandate guns for all except those who explicitly don't want them. Britain chose the first option; it doesn't appear to work very well there. We've chosen the second, although we used to follow the third. Switzerland follows the third option, and has an extremely low crime rate (of course, it's also a very small country with a very different social spirit).

    If just a few--maybe just one--person had had military training, he might have made a difference. If just one other person had had a weapon, he might have made a difference. I think that we can see that our experiment in limited weapon-carrying has been a failure; we also see from the areas of the United States with the harshest gun laws (guns are banned in many areas) that weapons bans don't work.

    Might it be time to revive the Founders' militia ideal? They passed laws requiring every adult male to register in the militia and to outfit himself with a basic infantryman's kit (knapsack, rifle, ammunition, boots, belt and so forth). I'd add an opt-out provision for pacifists, but other than that would it perhaps be a good idea for folks to spend three weeks getting basic military training after high school? We could shrink the size of our Army (making it essentially a cadre of officers, NCOs & specialists to seed an activated militia) while at the same time making foreign adventures far less likely (militiamen, unlike soldiers, have the right not to fight).

    And it would help reduce the death toll in incidents like this.

As he's being arrested, a wit in the crowd points out that the kid has created a job for the glazier, who can now buy a new suit from the tailor, who cna buy bread from the baker and so forth.

    Dude, it was an example. The really interesting thing is that even if China is better at producing both maize and wheat, it's better for it to focus on the one it does best, leaving the rest for everyone else in the world. Besides, even if China did end up producing both wheat and maize more cheaply than us, how are we harmed? We'd have more wheat and maize for less money. Paying less for the essentials of life is generally considered a good thing. And of course folks paying less for food means that they've more to pay for other things.

    That's kinda the point of economic efficiency: everyone has more goods than they would otherwise. And that's the problem with economic inefficiency: (on average) everyone ends up poorer than they would otherwise.

You should owe your employer nothing more than your labour; your employer should owe you nothing more than your wages. If someone else can provide the same labour for fewer wages (or more labour for the same wages), your employer should contract with that person instead; if someone else can provide the same wages for less labour (or more wages for the same labour) then you should contract with that employer instead.

    I don't owe Safeway my patronage; if I discover a better price at Albertson's then I'll buy there. Why should an employer be any different?

    The biggest problem in my eyes is that in America currently, employers want all the benefits of the old system with none of the costs. That is, rather than negotiating a proper contract with each employment, one which spells out exactly what is required from each party and under what terms (e.g. 40 hours a week, time-and-a-half overtime, no more than twenty hours of overtime may be compelled), and under what conditions the contract may be ended (e.g. with two weeks' notice)--instead of doing this, they want every employee to be employed at-will, with even work done on personal time to belong to the employer. This is a relic of the old-fashioned semi-feudal way of doing things.

    It's highly advantageous to the employer, but rather negatively so to the employee.

    The real solution is for all of us to be under a firm, negotiated contract. When a corporation provides a service to another corporation, there's a contract involved. When you or I provide a service to a corporation, most of the time there's only an implied contract.

    For that matter, why do they 'need' to encourage folks to vote? Voting is a privilege, and if one chooses not to exercise that privilege, that's one's own look-out.

    It seems to me that the right thing to do is to discourage voting. Charging $20 (or the equivalent in your local currency--10 pounds over in the UK) to vote; it's not so much that it's unaffordable for anyone (indeed, even the poor spend more than that on beer and cigarettes in a week), but it's enough to make folks think before voting. Even better would be to give a simple test: pick the current holder of the seat for which you're voting; if you don't even know who's currently holding that seat, do you really have any business voting? Ideally, the franchise would be limited: have a slate of perhaps two dozen different qualifications (e.g. college degree; married with three or more children; salary of $50,000/year or more; net worth of $100,000 or more; ownership of 4 or more acres of land; prior or current military service; jury service within the last year; IQ of 95 or greater; prior holder of public office; and so forth), and anyone who meets three of them can vote. Make it a fairly broad slate--my suggestions are from the perspective of a middle-class citizen, but no doubt others could suggest appropriate qualifications (union leadership, maybe?).

    The problem is not that too few people vote; it is that too many do. The margin of victory in the popular vote in the recent presidential elections has been less than the number of people with 80 IQs: when the side that can swing the most mental defectives is the victor, that can't be good.

    That's a fair perspective if you believe that the cost of a comparable solar system will increase over time. As an example, let's just say that you pay a constant $3,000/year on electricity, and that a $30,000 solar system would reduce that to $0, and that you could otherwise make 4% on an investment, but that you also have reason to believe that a solar system will get 2% more expensive every year. After a decade, you would have an opportunity cost of $14,407 by going with the solar system and would have spent $30,000 for the system itself, but would have saved $30,000 in electricity bills (you're out a net $14,407); on the other hand, if you'd invested the money you would have spent $30,000 on electricity, saved $30,000 on the system and made $14,407--but the cost of buying a solar system at that point would be $36,570. In other words, as long as the appreciation in the cost of a solar system is less than you could make in another investment, all other things being equal you're better off postponing the purchase.

    But of course in real life solar systems, as with most technology, get cheaper over time. You'd have been better off waiting eight years and buying a solar system for a fraction of the cost (maybe 85%, say).

    And your 7% return is not correct as it doesn't take into account my marginal rate of taxation which would reduce the ROI to under 4%.

    I think you only need to pay capital gains when the investment is sold, although you would need to pay income tax on dividends. But you do raise an important point: one does need to take into account the effects of taxation & inflation, especially over longish periods of time. A 2% annual inflation rate means that $100,000 in 2017 would be worth $82,000 in today's money, and the effects of taxation can make an otherwise sensible investment insane (or an insane one sensible).

    As an alternative, I could have paid for my installation without laying out any of my own money by taking out a mortgage loan and repaying the loan out of the savings. This works rather well because this is a home improvement so the interest is tax deductible.

    The interest is tax deductible, but that just means it's subtracted from what you earn. That means that for every $100 you pay in interest you save at most $33. Paying $33 to save $100 is brilliant; paying $100 to save $33 is nonsensical. Not that tax advantages can't make a difference at the margins, but in general it is almost always better to pay cash than to borrow money (the exception is when you can generate a greater rate of return with the cash than you'd pay in interest; this is effectively leverage, borrowing money at, say, 4% and making money at %12 can be quite remunerative).

    None of this is to say that you shouldn't have gone with a solar system; one also has to factor in the advantages of feeling good about oneself, of being more self-sufficient and of knowing that one is advancing technology.
