    Not always, but that is a very common and prevalent problem. Math techniques and proofs often don't yield insight into how or why they were developed. For example, when I do analysis proofs, it's common for me to calculate what tolerances will lead to the desired result and then strip those calculations away for the final proof.

    "Why did he pick this delta or set that coefficient to that value?" Because I figured out what would work well enough and got rid of the scaffolding. Here, you see the finished result, not what went into finding the finished result.

    Good math books discuss the scaffolding in detail not just the proofs or techniques.

    You do realize that most attempts to preserve Western labor privilege have the unintended consequence of hastening that race to the bottom? Bottom line is that currently there's vastly more supply of labor available to the Western markets

    You second statement disproves your first. Most of the increase in labor is coming from China and other rising countries. Those countries do not answer to America or those who attempt to preserve Western labor privilege. Those attempts do not speed up (nor slow down) that increase in the labor pool.

    Where's the contradiction? To disprove, you have to show that the one statement somehow runs against the other. It doesn't happen here. Note that I explain how the attempts fail to improve the situation by raising the cost of developed world labor not by increasing the overall size of the global labor pool.

    Or put it another way: it's not your (West) fault that China is becoming better than you, much like how it's not Europe's fault that America became better than them in prior centuries.

    If that were only true. It's not though. There's no inherent advantage to being Chinese any more than there was an inherent advantage to being American back in the day. Where was the economic opportunity for all those ethnic groups of Europe who fled to the US in the 19th century? It was in the US. The profound injustice, lack of economic opportunity, and sometimes just the need to survive drove many people out of Europe.

    Obviously, the developed world is a better place than it was then. The failures of today are not those of yesterday.

    Then feel free to suggest that other way. Better yet, implement it yourself (convince some investors to help you if you must). You could become a second coming of Henry Ford and become rich as a result.

    Ok, end most entitlements, be they social welfare or business. End minimum wage. Greatly reduce regulation of businesses and people and for that regulation which you keep work on finding ways to make it less onerous for those that to comply.

    I find your "Henry Ford" comment telling. It's not a innovation matter or something that can be fixed with a business. It's a matter, as I wrote, of getting rid of the societal and political attempts to preserve an ideal of privilege that is no longer sustainable.

    The develop world collectively values capital over labor

    Yea right. Guantanamo is still a few centuries shy of the Spanish Inquisition and fundamentally, it's a POW camp. Indefinite imprisonment legally goes with that territory. The war which it's associated with is some nebulous affair that might drag on for generations or it might be ended in a legal sense in a few years. I think the Guantanamo Bay prison is unjust, but it's not at the level of the Spanish Inquisition.

    There's also the matter of number of prisoners and punishments meted out. Current number of prisoners in Guantanamo is less than two hundred.

    No. Such things are considered wealth because they either have value to someone or they can be exchanged for things that have value to someone.

    It is the trade in goods, resources and, skills that define value and hence wealth.

    No. It is the goods, resources, and skills that have value to someone and hence, are wealth. Trade expedites the matching of the providing of such things to those who need such things. Yes, it does create wealth by enabling cooperative behavior that wouldn't exist in the absence of the trade. But the trade itself is not the wealth.

    Your simpleton view, that somehow you can survive in a capitalistic world sitting on your meaningless hoard without spending it and creating economic activity, is just so unfathomably ignorant.

    Well, you're clearly not the person to enlighten me. You don't even understand the point of trade.

    For an example of why economic activity is not wealth, disasters routinely encourage economic activity while simultaneously destroying wealth.

    Look at the post I replied to. Original poster was whining about how every dollar (or other unit of currency) that a government spends was taken from someone. His response was that that the money seized would be spent multiple times (In practice less than two times). Note the mismatch of meaning, wealth is compared to activity (not even GDP which can be construed as a weak measure of wealth creation, but merely activity). This is deceptive since as in the example above, you can easily have considerable economic activity in the presence of wealth destruction.

    In my link above, I discuss the "SNAP" program which is some sort of food assistance program in the US. They use the same obnoxious deception. $5 of wealth becomes $9 of economic activity. Apples are compared to oranges.

    If we were doing a legitimate comparison, it would be $5 of wealth resulted in a person getting some food (which they could have otherwise obtained themselves) and that's it. The economic activity would have no real value since the $5 taxed would also have been used for such purposes or for investment (what you call "hoarding"). So $5 of someone's money is used for fairly frivolous purposes (much less than $5 of value).

    How much do you really think that's going to change the price of oil? I think the last time I checked such things, even if we tossed the entire US military complex as a tax on gasoline, that would mean a few dollars per gallon tax. AGW costs in Europe are priced at a few dollars per ton of CO2 emitted (which is on the order of cents per gallon of gasoline).

    Of course, the opposite will happen: the West will race to the bottom on labour conditions and freedoms.

    You do realize that most attempts to preserve Western labor privilege have the unintended consequence of hastening that race to the bottom? Bottom line is that currently there's vastly more supply of labor available to the Western markets than there was decades ago - hence, the price of labor is going to decline no matter how much you complain. It's basic supply and demand.

    Rather than find ways to make your country's labor more competitive (merely reducing wages is one way, but not the only way), the developed world collectively seems to be about how to restrict Western labor markets and adding even more costs to Western labor to encourage even more business flight to the developing world.

    The government is just as capable of producing wealth as any other entity.

    Capable != actually doing it. The private world has the profit motive for keeping it productive. The activity has to generate some sort of value to the actor beyond its cost or it isn't generating a profit.

    If the government spends money on a program that adds more value to the economy than the cost of the program (such as food assistance, which has close to a 2:1 return), then the government has produced wealth.

    Where is this study that claims a 2:1 return? I decided to google for this and came across this study. The money quote:

    SNAP brings Federal dollars into communities in the form of benefits which are redeemed by SNAP participants at local stores. These benefits ripple throughout the economies of the community, State, and Nation. For example:

    * Every $5 in new SNAP benefits generates $9.00 in total community spending.
    * Every additional dollarâ(TM)s worth of SNAP benefits generates 17 to 47 cents of new spending on food.
    * On average, $1 billion of retail food demand by SNAP recipients generates close to 3,000 farm jobs.

    Note that $5 in spending produces $9 in spending not wealth. So right there we don't have a 2:1 return. As I see it, we take $5 of someone's money and use it to generate far less than $5 of value - feeding someone who can feed themselves. That's negative return on investment right there.

    It's a destructive economic gimmick to conflate spending or economic activity with wealth creation. They aren't equivalent or even correlated. For example, a disaster creates a lot of spending and economic activity (from reconstruction efforts), but it results in a net loss of wealth.

    If you know the math and understand it you still can teach the basic concepts behind that proof

    Sure, you have people like the Walton kids who have lots of money due to being the right human egg cells fertilized by the right sperm. They don't have a good claim to inherent business aptitude (unless that sort of thing is partly hereditary, which it might be). On the other hand, a Sam Walton, who parlayed a $20,000 family loan into a vast chain of retail stores (Walmart and Sam's Club) which had revenue of $50 billion by the time of his death, probably had some natural ability. For example, he apparently restarted his business in several different locations before it really caught on. That's not simple to move a business and start over from scratch more than once, much less turn it into one of the largest businesses of the day.

    So my view is that yes, you'll have a bunch of rich people who got lucky with who they were related to. But you also have the people who actually built up that wealth. I think that latter group (which actually consists of several different subgroups depending on the strategy used for wealth accumulation, some which can be rather underhanded or innovative) is very different from the normal population. There is a sample bias here which people aren't acknowledging.

Sure, being able to manage a billion dollars successfully may indicate that you are suitable for membership in some sort of ruling elite which is a dubious proposition in itself, but I remain puzzled why ruling is considered a good use of their talents.

    Why should we desire a politician Sam Walton over a businessman Sam Walton? To the contrary, I think having Walton as a businessman has worked much better for society and humanity than having him as a politician or government bureaucrat.

    And of course, there is the conflict of interest. I'm not better served by an extremely talented person who happens to be exercising that talent by robbing society blind.

    Suppose I'm inherently really good at swimming and training for and performing in swimming competitions. Should that qualify me for membership in the ruling elite? Suppose I'm naturally intelligent and pick up some hard degrees in college. Does that qualify me for membership in the ruling elite? I suspect from what you've wrote that the answer would be a resounding NO for all three cases above no matter how much natural advantage I might have or how much it might contribute to successful rule over others.

    Historically, having moral grounds or insight has never been that important of a criteria to be a ruler.
