I don't want legislators who think they're "running the country". That's the first problem. Rulemaking should never be construed with "running".
Secondly, I've never had any illusion about trying to attract "the best" in Congress. It's an elected position, both the House and Senate, and so it will merely attract those with aspirations of power and wealth who are good at campaigning. Oftentimes we also get people who forge a decades-long career by leveraging the access to power and influence they have in such a position. This last part is toxic, and won't be fixed by increasing pay.
