A lot of people think we fall into doomporm territory when we say that capitalism isn't a perfect system, but regardless of popular opinion, even if we take the US as an example which is supposed to be a shining example for everybody else to follow, the truth is that the US has been leading a war against half the entire world for several decades now from all out battles to black ops. The CIA itself is literally the biggest drug dealing group in the world. Yet people are either apathetic or completely ignorant towards the whole issue.
I guess the main issue I would say I have with capitalism is that it teaches people that their own confort and freedom is the greatest value they can have, which is all the more pushed by a lack of meaningful authorities in society. Money replaces virtue and people forget about the loyalty towards their own nation.
