It's interesting to hear you say it doesn't happen in nature as though we are outside of nature. It seems pretty clear that the phenomenon that is currently happening does happen naturally. Natural Selection isn't without local minima/maxima. Rapid environmental changes cause them all the time, and we've seen a lot of change in the last 100 years.

It sounds like you're conflating wealth inequality with capitalism. Those are two different concepts entirely. Capitalism with appropriate limits can lead to healthy competition, and a self-correcting economy without risk of a misguided government accidentally creating a bubble that then pops and hurts everyone. The government should specifically be there to pop bubbles before they become too big, and if they do get too big, ease the impact to its citizens as it deflates. Without the appropriate limitations in place, often times the best "capitalist" option is to buy government influence and cause exactly these kinds of bubbles to happen, benefit from it, and then step out of the way when it pops. Which is where we regularly find ourselves today. The issue is compounded by people using phrases like "just pick yourself up by your bootstraps" to justify a do-nothing government.

I agree with you about calling China "communist", but I was deliberate in my argument. It's not relevant that China is a totalitarian dictatorship, I was using them as an example of an entity that is decidedly not capitalist internally, but inevitably has to be externally.
