I remember reading a Sci Fi novel that had an interesting approach to Politics and makeing sure that Politicians did the best they could for their Country.
Losely, it went something like this:
When you became a politician, the goverment Audited everything you owned, and I mean EVERYTHING. It was assigned a cash value, which was then recorded in the books, and all your worldly possessions became property of the Government (most personal effects type things would go into storage).
You then served your term. During your term, the goverment covered all your living expenses, travel expenses and alloted you a spending allowance for personal Entertainment and the like. They also payed you an annual salary that was added to your initial cash value assessed when you first entered office.
At the end of your term, if the area you were responsable for governing / representing as a politician was better off then when you started there, you were payed back all of your initial Worth, + your salary, + a modifier based on the improvement you achieved during your term in office.
Likewise, if at the end of your term, the area you were responsable for governing / representing was WORSE off, you were fined an amount based on how much worse off the place was.
For example, If you were elected mayor of a town, that town OWNED you. Everything you owned became an asset of the town. If you served 10 years as mayor, and the town flourished, when you stepped down, you would get the proverbial "golden parachuite" and could retire comfortably for the rest of your life.
However, if you managed to fuck the town up due to mismanagement, when you retired, EVERYTHING YOU OWNED might be confiscated by the town as a sort of settlement to cover the cost of repairing the damage you had done.
If the town was only slightly worse off, you might end up retiring with your intial net worth + some of your salary. If the town was really badly mismanaged, you could retire a penniless beggar.
The only catch I remember from the books (it has been a long time) was that Political office was generally not something a lot of people voluntarily wanted to do, given the nature of the risks involved, so many of the people given Political office were usually "forcefully" appointed to the post, and once there you were stuck for the full term. Generally, whoever ended up drawing the short stick was someone qualified for it tho, not just some random schmuck off the street. So one of the dangers of being a Princeton Politics grad or something similar was that you could end up forcefully elected to office for 5 years.
If Modern Politicians had that kind of Incentive hanging over their heads to stop all the bullshit and actually serve the people / properly manage the places they represent, do you think things would be a lot better then they are now?
