A simple idea

Those charged with piloting the ship of state will inevitably have conflicts of interest between private investments and public good. So why not propose that upon reaching office, they must give away all thier assets to the state? One could argue that this would make them more suceptible to bribes, but I disagree. If they are given a very tight stipend, and must live very modestly, than any corruption or bribery would be immediately detected, as it would be known that they did not have enough money to buy a car, or take a golfing trip, or hold stock options.
