Ok, but, like, no offense, are you skilled enough to properly analyze and dig through large complicated bills? Are you a skilled enough administrator to manage an office of staffers?

Are most politicians? They generally use their staff and their chief of staff for those things. The only thing that I'd grant them across the board, generally, is they are decent at public speaking.

There are many people that have specialized training that do their work to serve, not for the money (e.g. teachers, public defenders, MSF, etc…)
