You clearly have misinterpreted what the word “capitalism” means. You’re spot on in describing the most major problem of the world — extractive practices. But capitalism doesn’t mean what you seem to think it means. The extractive practices (colonialism, marginalization, wealth extraction) you are talking about all come from *government* actions. You and I agree on the problem, but you’re doing the cause a HUGE disservice by trying to label that problem as “capitalism”.
Capitalism is private management of resources, socialism is government management of resources, plain and simple. Don’t complicate things by pretending that capitalism is an enchirideon sized procedure for extracting wealth from the masses. Its not. Its a lot harder to show that socialism isn’t that tho.. All the things you’re talking about are better described as problems with socialism, not capitalism.
