Off the cuff maybe we could offer voter based incentives. Annually after election the constituents can vote whether or not the official earned a bonus.

I don't mind greedy bastards. Money, shame and pride are powerful motivations.

Unpopular opinion but I'd like to just pay them more. Like I said I don't mind if they're just in it for the money as long as they're the best at what they do. Elected official is a job and most people want the best paying job they can get which leaves us with people who couldn't cut it in the private sector.
