So long as they don't confront capitalism itself, identity-based liberation movements won't put an end to injustice and inequality. Being exploited by people like yourself is hardly an improvement on being exploited by people different from you. Even if we could all experience equal opportunity within capitalism--even if domination and exploitation could be distributed without reference to race, gender, or any other axis of oppression--capitalism itself would still be oppression.

[...] If we want to transform our society, we must not only overturn institutions but also identify the functions they serve, lest we end up taking on these roles ourselves. Even without capital or police, entirely new currencies might arise to impose oppression and alienation.

There's no reason to believe the downfall of capitalism will automatically bring about a free world. That part is up to us.
