This is the case all over the Western world. Federal Government politician salaries need to be 10x higher.
The history of unpaid and low-paid legislatures (of which there is quite a lot) does not really support this idea.
Congress gets paid like 174k a year. Sure, it's a lot of money compared to the US median, but anyone who can get elected to Congress can earn that elsewhere.
For tech, 174k isn't even a big salary; we're talking an industry where a starting SE salary at a FAANG is around there. That's not a huge paycheck for a 24/7 job like federal politics.
You're describing what we already have.
The argument being made is that if you're going to pay people a low wage, they'll just increase it by trading some of the power they yield in exchange for money for themselves, which is the problem we're trying to solve for :)
In fact, that might be the reason that politicians are paid so poorly now: they can just be drawn from the pool of political insiders and parachuted into districts.
Like another poster said, political term limits of 10 years in combination with this seems reasonable.
I don't want people making careers out of politics. Nothing good comes of that.
