TBF I think most people in power are very comfortable with the profitable arrangement they have, so I don't see many/any of them going along with a revolutionary plan (unless they would end up in prison otherwise). Is it really worth the hassle if you can just stay in office and end up a multi-millionaire via inside trading? Let the populous deal with the real world
Pfft, did you buy it? No? Then it's not yours
That "representative republic" belongs to a handful of ultra-wealthy people. I expect the Founding Fathers, being almost all rich old white men, would have approved. The French know how to actually build a republic, this is their fifth attempt so they're getting pretty good at it. Maybe ask them to help with the next one.
