1. Gun Control
Very little gun control is needed. From sniper rifles to assault rifles to pistols, I think anyone who can afford a weapon they want should be able to purchase one.
2. Unemployment
Globalization has put a lot of Americans out of a job. I don't know what to do about this.
But, on a related note, affirmative action is bullstuff. There should be no quotas for hiring minorities or accepting them into colleges. If you want to only hire white people, that's your own business. If it fails, maybe next time you'll hire more black people. If it succeeds, good for you.
