There is the question of what we mean by capitalism. Is capitalism simply the state of affairs of contemporary Western society? In that case, capitalism includes things like labor unions, state regulations, corruption, etc. So the word refers to a very dynamic and tumultuous process involving constant struggle between opposing forces. That's never going to be a "perfect system" of course. What we think of as opposition to capitalism is then a big part of how the system regulates itself. But maybe capitalism is more correctly thought of as a certain set of forces and structures operating in the larger state of affairs. For example, capitalism is whatever is advocated for by those who own and manage concentrated capital. Then, too, opposing this should be natural for anyone who doesn't belong to that class and doesn't expect to. I'm just saying that the concept "capitalism" deserves analysis if we want to talk about whether it's good or bad and to what degree "we" should oppose it or try to change it.
