My wake-up call was the COVID pandemic.
When the rest of the world sent "essential workers" like me off to die while China stayed locked down, I had to reevaluate everything I thought I knew. If China had completely abandoned the revolution, I thought, why would they put the lives of workers ahead of profits and growth? Surely if they were just some kind of authoritarian capitalist state they'd have marched their workers off to die the same as my country did!
And they didn't. And they kept not doing it, long after the rest of the world was screaming for them to open up the economy.
Any Westerner that still believes China has completely betrayed the revolution needs to explain why and how this happened.
