MTG hasn't yet figured out how to get rich while in office. Some offer up term limits as a solution to prevent congressmen (women) from staying in office to long. Another way is to prevent them from becoming rich after they get in office. Prevent them, their family members and staff from trading in individual stocks. Make the same rules against insider trading apply to them, their staff and family members as well.

Also, something has to be done about their PACs. Tighten up the rules on how PAC money can be used. Force PACs to payout a certain percentage of its assets each year for approved political activities; pretty much like what is "supposed" to be done for foundations.

Serving in congress shouldn't be a lifetime job.

There is an argument to be made for why congress' salaries should be increased

I don't think their salaries should be increased but they should be given a housing and living allowance while serving in congress. Furthermore, their travel to and from their districts should also be covered.
