"Nobody is suggesting that we “prevent people from getting rich” or “end all economic inequality”."
FWIW, I've met tons of people who suggested this. Eg., at Google, I had a co-worker who was probably the best programmer on our team. He loudly and repeatedly argued for socialism (he literally used the word "socialism"), and for government seizure of all private property over some low-ish threshold per person. He very strongly believed that no one could ever earn the right to be rich, and that rich people were so bad for democracy that well-run countries shouldn't have any.
