I've talked a bit about it on here before, but as cool as guillotines and such are, the path of least resistance (especially in the short term) is to simply buy the bourgeoisie out. The key follow up to that is to decommodify property (especially housing) and key industries (and keep working from there ofc), so that it becomes incredibly difficult to stretch that 5 million bucks into any sort of generational wealth. After a few generations it'd have to be spent and gone.

A violent revolution may be necessary (the threat of one definitely is), but it has a higher potential to lead to right wing radicalization that socialists would have to deal with for decades (if not hundreds of years). Maybe that's the better option, but we aren't in any sort of place to make that sort of decision right now anyway.
