i dont support taxing rich people because i think wealth inequality is not a solvable problem

the wealth tax idea is a band-aid solution to a much deeper problem which is that the material and financial economies have diverged permanently. the guy you posted in the OP likes to explain the intricacies of the financial system and its injustices but he gets lost in the sauce imo because the financial system is a zero-sum game and it must eventually reckon with the physical reality that there is not enough stuff. this guy explains it well at this timestamp
