Fix crony capitalism by reducing bureaucracy and monopoly encouraging laws, I think that will reduce the extremely large monopoly companies that create / generate extreme wealth for relatively few.
As to fixing the money, there's a little something called Bitcoin, you may have heard of it 😜
Some rich wont give a shit, that's human nature. But convincing successful people that rising discontent may see their heads on a pike should motivate plenty!
Also need to drastically reduce the size and authority of government, currently its too powerful and causing too much tension over who gets to lead it.
