>I've checked wikipedia and it seems that affirmative action that was designed to remove all those inequalities was introduced something like 30 years ago, so one generation lives in the environment without discrimination.

The conclusion ("one generation lives in the environment without discrimination") doesn't come from the premise (that affirmative action was introduced 30 years ago).

Yes, affirmative action was introduced 30 years ago. But it hardly put an end to discrimination (among other reasons, because even if affirmative action was great, well applied and totally effective, discrimination is not constrained in the domains that affirmative action affects).

Affirmative action is hamstrung in many ways and also is fighting against one of the strongest social forces in US history. Why would we expect it to fix everything in a generation if it works? The fact that racial bias remains a huge problem does not prove that affirmative action is useless.

These equality & inclusivity departments do work. Not by including minorities mind you. They work by excluding white people, making them feel unwelcome by constantly reminding them how everything bad in the world is their fault, and firing them when twitter demands it.

Even if this is true (I don't think they have that much power), why do you think this is what minorities would want? They don't want to be treated as equals and have opportunities, they want to make white people feel bad?

The issue is that D&I had no power to do things that actually matter. I've complained to D&I teams before and they really exist to placate people internally because leadership will never change. When something gets out that seems like a bad PR problem ("twitter"), then the leadership team will take acute action and fire someone and pin it on inclusion.

It's a bad system for everyone but it's born out of cyclical system where white people do nothing about racism until it reaches some breaking point, then they insist on taking immediate action to "fix it" for a month, then they go back to the same old.

It’s born out of a system that seeks to protect the owners of capital by scapegoating the workers and making it the workers problem, rather than the problem of the people with the political power and money to make meaningful change.
