Let's not perfect be the enemy of good. OP is making a relative judgement, not an absolute one. And in authoritarian countries, figures like Jack Ma are dissappeared for far less, while radicals like you mention are just shot and silenced. You are not going to be allowed to build a alternative power structure that can challenge authority regardless if your views are valid or not.
Might be a hard metric for some people to confront, but the USA is one the least racist countries in the world. The gridlock in many ways is strongest signal of excessive plurality and minoritarianism (of marginalized groups) than of single power groups unilaterally controlling things.
Jack Ma was not, in fact, disappeared, though? He lay low for several months while being investigated for financial crimes. He is still the largest stakeholder in Alibaba, and still has a net worth around $27B. It's not even like his assets were frozen.
Disappearing for 6 months immediately after making a controversial speech about the financial system dosen't look good to investors. And we all know it's because of his speech, not because of "financial" crimes when the Ant Group is heavily works with the CCP given the scale of its activities.
