Capitalism is only sustainable within respective ethnostates. Capitalism for and in white countries, capitalism for and in black countries etc.
I have seen a few study reports that claim that the various ethnic groups in the world measure differently in regard to average IQ. I don't know enuff to judge the accuracy of these reports but regardless of accuracy the general idea of evolution to different IQ levels suggests that the various groups should remain in their place and whether the economy is capitalist or socialist the populations will be working and competing in the same range of IQ's. This is therefore an argument against multiculturalism.
Care to explain? What does race have to do with it?
Immigration has to be highly regulated in any functioning civilization in order for it to remain sustainable. No society can last long if there are many opposing ideologies and no social cohesion. Such a society is just asking for it's different members to be turned against each other.
@rudeawakening I think capitalism unites people, generally. I can be friendly and honest and caring with others while trading with them, even if I don't agree with their ideology....or if I don't even know their ideology. Libertarian ideology, for example, seems not to value highly regulated borders, as long as free trade is allowed. I think I understand your points about social cohesion. The two opposing views of government and economics would seem to incompatible...which seems to be leading to a divided house or society that cannot stand.
@rudeawakening "Such a society is just asking for it's different members to be turned against each other."
We've been asking for it for a couple hundred years.
Now we have it in spades.
