In the US, we've chosen the private sector to remunerate our officials after they've left public service, and our lovely government is the result.
Keep in mind that, as a public official earning top wages (~$150k/year) in DC, you can just afford to buy the median home in the area. But if you want a nice house (single-family) in a good neighborhood? Forget it! Whereas if you took your skills to the private sector, finding a place to raise your family would not be a major concern.
Singapore is an extreme example of this (perhaps too extreme) - the Prime Minister earns over $1.5M a year.
Actually the first family does have to pay for many incidentals, like every day food, and it comes in the form of a bill.
I don't see who this applies to in your last election
Of course, the President doesn't really have bills. He or she doesn't exactly pay to rent the White House.
