The United States should try to end discrimination only because they should never have let it happen in the first place! When the White man brought slaves to this country and then tried to keep them slaves even after they were declared free, it started and has not stopped since. Now we even have discrimination within our own races. It needs to stop because no one race or person is any better than the other and never will be!
The U.S. should try to end discrimination because regardless of our skin color, we are all the same - we're people. We will have differences as far as our culture but we should embrace and learn from those differences.
Discrimination should be ended in any part of the world, not only the United States. The US should try to end it because it is important to emphasize our equality as human beings and our skin-color/age/gender should not interfere with this concept.
The U.S. should try to end discrimination and let everyone be treated the same. We shouldn't be judged by our wealth, the color of our skin, what part of town we live in or the family we come from. We are all human beings and need to live together united, not against each other.
