It's a populist trope, as if you could elect the hundreds of thousands of people that are required so that the government can even exist.

Nothing, really.

The big problem is that now Trump has politicized the entire government, including a bunch of boring paper-shuffling agencies that have been largely nonpartisan with career civil servants who persist for decades regardless of the president.

A bit of an aside, but Trump making himself the chair of the Kennedy Center has got to be one of the biggest shows of ego that I can think of.
