So, if the UAE got oil money, don't you think the US got money from generous natural resources, too, especially lots of land, in the beginning? Capitalism is not about hard work, it is about investing money to make a profit. That is why it is called capitalism instead of laborism.
If that is true how did capitalism get started? Where did the initial money come from??
Capitalism is not about "investing existing money" it is about investing one's ability and hard work to produce something that never existed before, ie new wealth, or capital. Capitalism is about producing goods that never existed before and exchanging them for money, or profit.
Capitalism is not speculating in the futures markets, that is just churning existing capital, and it is not winning a class action law suit, these are just examples of a couple of capitalism's parasites.
Natural resources are meaningless and worthless without applying human ability and hard work to turn them into something that never existed before and something desirable to other human beings. Capitalism says you get to keep what you worked for, ie profit. Profit is the motivator to invest one's ability and hard work. That is the difference between capitalism and economic systems in which the motivator is the good of your fellow man. The US did not "get money from generous natural resources in the beginning", its citizens busted their butts investing ability and hard work to create new wealth using those natural resources, no one handed it to us. And we didn't rip off an existing industry built through someone else's ability and hard work, no, we earned it for ourselves.
Have you by chance read Ayn Rand's Atlas Shrugged? That book shows how true hands off capitalism works more than any other source I know of. I highly recommend it.
