> You only want people as politicians because they feel it's their civic duty to serve their countrymen, not because it's a lucrative career.

Why? I mean you just say that as if it's some universal truth. I don't see how focusing on civic duty is any better as a way to find good candidates than optimizing for high achieving people looking for lucrative fields to work on. I don't know which would yield better results but none is better by default in my view unless you have some romantic view of what politics should be, rather than what it is, a job.
