Democratic countries will eventually vote to limit the income and ownership of assests by the wealthy.
According to the wealthy people do things that benefits themselves. The middle-class will eventually strike back at the hollowing out of the middle-class by voting against feudalism, the current form of feudalism is Reaganomics which state the money harvested by the wealthy is their money which cannot be touched by the people who aren't wealthy. Nor should the wealthy have any responsibility to others nor any accountability for their actions.
This feudalistic attitude is responsible for the economic ups and downs. To smooth economic waves and elongating any economic cycles the wealthy must be limited by democratic voting.
By pushing wealth just to the wealthy creates supply-side economies which ussually means the end of an economic cycle with recession.
The wealthy are very bad investors: most of their wealth is not due to good investing.
