I appreciate making some peoples nomination lists and I will outline my modest social reforms below.
First: Women should not be able to drive, vote or go out in public without a man. They should be required to wear concealing garb at all times. See fig 1. If they do not comply they should be stoned to death. Second if women are raped they should be stoned to death or the punishment should fit the crime and they should be raped again. Common sense. Homosexuals are allowed to marry each other but sodomites get stoned to death. Also gypsies, the Irish and the NE Patriots should be stoned to death. If you drink alcohol you should get a hand chopped off or you can elect to be stoned to death, also if you grow lots marijuana you should be locked in prison for life or stoned to death, your choice.

Second: We create a banking system where people deposit money into banks and then the banks lend out 20x that amount. We'll call it fractional reserve banking and it will create a stable and equal economic system. Those who end up bankrupt pr poor inevitably drink alcohol or try to grow pot and get stoned to death keeping the amount of undesirables at a minimum and eliminating the poor making everyone rich.
