The USA is also a good example how the markets can get in the way of the regulation and of free markets. The players in the free market don’t really benefit from being in a free market. They have every incentive to change that.
Is that capitalism destroying itself tho? I mean in a purist way, what you describe is capitalism changing so it does do something but what it ends up in is called late stage capitalism so did it really destroy itself or merely “evolved”? Yes in that stage it is worse for 99.99% of people compared to before but maybe that’s somewhat intended? And most importantly is that stage (more) stable or not.
