Live off the taxpayers, drawing a retirement pension that is the envy of many C E O's, enjoying full Secret Service protection for themselves, their spouses, and all of their children, and give short, usually pointless, speeches for astronomical fees. Then, in their spare time, they call in all of the favors that you granted to various people of power, foreign and domestic, they you were in office. And, of course, there are book deals, TV appearances, "technical advisor" gigs for astronomical fees, and setting up tax free foundations that provide assistance to needy groups on a pay for play basis.
And, no, I'm not talking about any specific exPOTUS or ex First Lady. They ALL do most, if not all, of that.
(I'm not cynical, just old, tired, and fed up with politics and career politicians)
