Also how do you avoid billionaires worldwide? Not everyone lives under your government. Even if you could, how do you know for a fact that some people don't secretly control hidden assets? Is Xi openly a billionaire? China is a "communist" country on paper. How does he hold so much power?

The sad reality is that the world has a nonzero percentage of power-hungry narcissists. We need governments that are more democratic and robust. We all know that the current government processes are broken and corrupted.
