This is basically a list of things that are wrong with the U.S. or problems in the world.

I don't understand how this proves that capitalism is bad. If the world still hasn't solved all its problems, then capitalism is inherently bad?

By all metrics, the world is much much better now than it was 100 years ago. And it's mostly thanks to market economy.

All countries that have tried something different have had to resort to some flavour of capitalism in order to have any meaningful development.

Also, nobody said our economic system in its current form it's perfect.
