I have a hot take on this that I think could actually make some headway: - We raise the congressional salary. Say, maybe double them across the board.

BUT in exchange, you, your immediate family, and any business, LLC, or other similar vehicle you are a named party to as a consultant, beneficiary, owner, or investor must divest of specific investments and can only hold the equivalent value of an index fund that tracks the general market. Or, you can remove yourself from the investment/ownership vehicle during the term you serve as a congressperson.

Problem solved? Probably not, but it's an interesting thought experiment. I'm sure there are a bunch of loopholes I haven't fully through through, too.
