2) Determine a good health care system that helps citizens who have paid their taxes. If you have a condition, there's no reason you should be killing yourself just to pay for the medication that keeps you alive. Seems redundant right?
3) Fix the education system. We all know the US is falling behind rapidly. But globally,we need to make education much more accessible, and even mandatory up to a certain point. With the technology available today, there should be no excuse for any child to be left uneducated. Education kills ignorance and ignorance kills a lot of other negative things.
4)End Racism/ Stereotyping. We all do it. Usually we end up pleasantly surprised and befriend people we normally thought we couldn't. Don't forget everyone has things they are going through, but everyone also has inner beauty.
5) Declare Gang members terrorists/ make it illegal to be a gang member. This would wipe out about 25% of some cities' population, but crime would go down significantly and some neighborhoods would be restored. People live in fear around the world paying taxes to gangs. That is beyond heinous.
