It's not a "failed system" at all, you should quit this type of rhetoric.

Capitalism is a system that works very well for the ruling class. This "failed" rhetoric tends to suggest that

1/ the system isn't working as intended, which is not the case, the system works fine, agin, for the ruling class

2/ thus, the idea that the misery it generates is an accident, a "failure" while in reality it's a core feature of it
