The politician has a racket that is akin to that of a Mafia boss of bosses. He is paid a salary by all the taxpayer-victims. The underbosses then pay him to enable their robbery of the victims. This he does in the least invasive way. The underbosses also pay him to convince the victims that they are not being robbed, which he also accomplishes. The underbosses make enough out of these exchanges that they are gainers, net of all their costs which include their small share of salaries and their donations.
