How about they do their jobs, and put off making money in other ways till after their term ends. Maybe they can buy government bonds.
I think if we raised salaries your sentiment could work, but good luck with that.
Is the CEO of Tesla (~50B ?) really more impactful than the US president (~400k/yr) ?
Rich people whining about not being super mega rich. Fuck these asshats.
How about a public service that DOESN'T attract people who's primary directive is get ridiculously wealthy?
I suspect government is actually not nearly as lucrative as non-government and that's why people who "don't have the skills" are in government.
But if they're making say ~2M/yr then there's very little reason to go lenient on a company so that they'll give you a retirement job there afterwards. It also means that if somebody wants to bribe you then the bribe has to be rather large as you're both risking that salary and you also certainly don't need that bribe. (Although I do also think the government should stop footing the bill for a lot of the stuff the congress critters do and if you want to spend 1/2 your presidency golfing that comes at your own expense).
The salaries of government people has filter down affects though as federal employees cannot make more than the vice president (~261,400).
