The super-rich hate the free market, because the market entails change, and for the billionaires, the only way open to them by any change is down.
They feel threatened because new, more vigorous, and still unknown entrepreneurs constantly arise to challenge their vested interests. If the super-rich could conspire to freeze society and prevent further disequilibration, then their wealth and power would be forever safe. They and their enterprises could then become lazy and conservative and ignore the demands of the consumers, rather like the government Post Office.
We should celebrate the past achievements of the super-rich in getting from rags to riches, thereby making all of us better off, but distrust their present political machinations, aimed as they inevitably are at destroying free competition.
The older Jeff Bezos, Bill Gates, and so on get, the less competent at business they become, and the more eager they get to enlist the state to protect them from the competition by dangerous upstarts.
We must not allow them to succeed at feudalizing the economy.
