In America some changes I would like to see are a statewide approval of gay marriage. It is a little economy booster, plus it doesn't hurt anyone. Also better healthcare and a decrease in racial and ethicial problems because we still suffer from racism and discrimination in today's society. Also I feel people should become more environmentally aware because in the end all of these issues won't matter if there isn't a world to live in.
The biggest change I would like to enact in the world is to end prejudice and approve of interracial marriages. I believe this will allow society to actually come together as one and cooperate.
