They’re just different names for the rich and powerful walking on the backs of the poor.
No that's literally the name of capitalism, as capitalism refers to a system where socioeconomic power is primarily concentrated in the hands of a capitalist class, what you call "the rich and powerful." Their power stems from their richness, and their richness stems from their private control over the means of production, and thus the ability to extract surplus value from the labor of others. As Smith put it, wealth is ultimately the ability to "command" the labor of others.
Even if you voted in Socialism here, it’d just be a new set of faces keeping you down while they drink champagne and fly around in private jets.
I mean, if they did, that's not the fault of "socialism" but of a charlatan opportunist pretending to be one to trick the workers to enriching themselves.
This would be an equivalent fallacy to claiming that republicanism is equivalent to monarchism because some republican did not actually overthrow the monarchy but kept it in power while benefiting from it. That doesn't prove that republicanism is a lost cause or equivalent to monarchism, only that the specific republican was a traitor to the cause.
Scarcity exists for a reason under every “ism”.
The existence of scarcity doesn't imply that your society must be ruled by unelected oligarchs who rule at the expense of everyday working people. Genuinely I have no idea how you make that logical leap.
