The argument for capitalism is that it's raising literally billions of people out of extreme poverty - Zizek is clueless if he doesn't get this basic point. If you're a random poor person from China (especially the Chinese interior - urban and coastal areas have their own reasons to distrust too much democracy however), you don't care about democracy, period - capitalism (as in, good business) is your first priority, and basic liberal values (even Xi is focusing on things like fighting corruption and opportunistic behavior - that's the hidden dynamics behind the "social score system" controversy!) come second.
