The system favours the rich.Yeah, obviously. What system doesn't favor people who have more money?
That might be backward. Those favored by the system become rich.
The question is not how to get rid of rich people, its how to make a system that favors (makes wealthy) the honest and productive people.
Best practical answer and only moral answer is: A system that favors people who convince others that they're worth it without deception.
The fundamental error of "progressive" i.e. redistribution taxation is the notion that the system can be fixed after the fact. The only way the rich would not be deserving of their wealth is if they got it by force or fraud, and the only way to do that (legally) is through government. Furthermore government is supposed to prevent the illegal variations.
You don't "tax" criminals, you stop them, leaving only the government grifters.
Therefore what people keep asking for is "Give me a tax code where the enrichment from taxes and regulations accumulated as an unfair advantage by X is reversed."
It's asking a crime organization to make their victims whole by taking from themselves and giving to the victims.
The results are exactly what one would expect. No matter how high the taxes go, the rich keep getting richer. More accurately the people in on the scheme keep getting richer and the people who aren't keep getting poorer by comparison.
