Being removed from reality is a form of insanity itself.

A lot of people die from hunger daily in my country and different parts of the world. If you're speaking about growing wealth in developing countries, you should go look at the people holding these wealth, most times, it's an even smaller group of elites than in the USA.

Capitalism is wielded in a much worse manner in underdeveloped and developing countries, the elite and people in power don't care about the citizens, they want to hoard as much wealth as they can and they would do so in any way they can. What's worse, they take these wealth to already wealthy countries to further develop them while intentionally destroying theirs. Your should follow the flow of wealth from the global south to the north the west in particular.

Yes, in these countries there's a growing middle class, but what can they buy or do with the little wealth they hold? They're stuck in an endless struggle against totalitarian governments who are themselves stooges to global neocolonialist and imperialistic countries powers like the USA and European countries.
