I have seen some youtubers use the word central planner as an insult for government institutions. In my opinion there's a different class of central planners that nobody really gives a damn about. Billionaires influence governments and also have an outsize impact on the economy either by concentrating wealth and thereby denying that wealth to others or by directing their wealth on things that they personally care about but the majority of the economy does not.

The conventional trickle down hypothesis is that giving the rich money lets them do their job more efficiently because of centralization. That is basically a belief that only people who do not believe in a liberal(or free) market would have. The idea that 300 million decision makers are worse than a handful of billionaires is absurd. If the work of these billionaires is truly needed then let people make that decision for themselves and give them the option to avoid them.
