As far as I understand it there has been a few legislative pincher moves since inception. The 17th amendment might qualify as one. It allowed for a populist instead of representative vote of our senators and basically created the modern situation of whomever spends the most campaign money wins. AKA special interest/lobby groups now rule.

That is one of of the few small changes of course the country made that if reversed would probably be to the benefit of most. To revoke the 17th would be senators literally voting themselves out of work, hence it would never happen. A soviet style collapse is a revolution too, just forced and likely crummy.
