This could use a bit more explanation and CGP Grey actually has a very good video out called "The Rules for Rulers" which touches on one of the reasons this really is a terrible situation. Whenever funds are diverted to the common good the party in power is, by definition, kicking less money into cronyism than is possible - in a setting with a poorly activated public, where power ends up being concentrated into the hands of the few, there is a constant pressure from those in power to divert more money to those representative voices from the voices you're unaccountable to - this makes it more likely that even a well intentioned leader will be ousted in a coup.
