So you want a bunch of people with no experience running the country? How many times in history has that not been a disaster?

Merely being in power for a long time does not create a "swamp", bad ethics does. Bad ethics is known to be enabled by secrecy and inhibited by transparency. The solution needs to address the actual cause, not some unverified assumption, so more transparency is far likelier to actually reduce corruption.

(And the guy who was going to "drain the swamp" was the swampiest guy around. Turns out he fights tooth and nail against any transparency into his affairs. Huh.)
