Far beyond limiting what members of congress or other high office holders can invest in while in office, I think the ideal should be that public office holders must play a Rawlsian gamble: when they leave office, we select a random citizen, and their level of wealth is wiped to match that citizen. Excess goes to a fund for public campaign financing. Not only should politicians not be incentivized to select policies which benefit them specifically, but they should be incentivized to select policies which materially benefit the population overall.
