Not allowing ex-felons to be employed by the govt. Not allowing jobs to discriminate based on criminal history (I know, I know, if you mark "yes" it will not necessarily bar you from employment ) Know too many people with this problem.
Allowing multiple parties. The two party system leads to us picking the lesser of two evils and polarizes people onto two sides. With three or more parties there would be give and take as well as a requirement to get along, at least enough to work together. These days whoever controls a house (Senate, House, state houses etc) doesn't care much about the people across the aisle.
