However, your other points: nobody is motivated by money. They want the 'wealth' it is convertable too. And wealth is all valuable things: medicine, automobiles, green energy, free range chicken, homes, etc.
'Wealth of Nations' Adam Smith? I don't recall him being that specific. The wealth of nations was largely an accounting of the wealth of Britain and his inquiry into the cause of it (capital, specialized labour, deregulation).

Actually I think I have a solution. If libertopia was better -- no skilled labour would move (or stay) in slavtopia. The few viable industries (diamond mining, oil & gas, lumber, etc) would expire as Libertopia naturally developed alternatives (like it already has: synthetics, electric cars, composite woods).
The transition period is messy though.
I would take it a step further and say that it was inferior in almost every way. There are individuals and organizations that behave with "brutal authority" in every society, but when it is the government and they have absolute (unchecked) power, then it is far worse.
The problem as I see it comes from trading with countries without high levels of worker safety standards and environmental standards. Also from not accounting for negative externalities. A tax on carbon would be useful. Things like that.
A man said many years ago that the love of money was the source of all evil and this, I think, is the crux with the problem of capitalism. Money is not a great motivator. Newton did not invent calculus to make billions. Leonardo would not have painted better if he had been paid more. I don't the answers to the problem but I do believe there is a huge problem with capitalism and, more specifically, corporatism.
Adam Smith opposed corporations because the externalities weren't accounted for (to use modern parlance). I agree with him on this. There are lots of examples of corporations acting in a brutally authoritarian way and the comment by nazgulnarsil seems to imply that by reading history one comes away with a view opposite to:
" fortune 500 company a "brutal authority" "
Again, I don't know the solution but there is a problem and plenty of examples of Fortune 500 companies acting with brutal authority.
EDIT: I'm not implying in any way that the Soviet Union was a model or that it ought to be emulated. I don't suggest communism as practiced by the Warsaw Pact nations was better than capitalism.
