How would you ideally change the US?

Enforce an official metric system over a five year period, ban flouridated water, ban trans fats, aspartame and high fructose corn syrup, disband the FCC, have the FTC actively sue scam artists, have conflict of interest regulations in the FDA and FTC, make Kosher labeling unconstitutional,  have more regulations on lobbying, give more government representation of third parties, eliminate funding to Israel, embargo Israel, dissolve the Federal Reserve, periodically replenish the Mexico border with landmines, and expel anyone of Jewish ethnicity to a Canadian reservation.  I'd like to see the first one happen, anyway.

Ideally for America. Change the way men are viewed and taught in this country. As it stands Aggressive behavior is seen as monsterous and punished. Effectively pussifying an entire nation. Women going to win wars for us? bitch please. We need to also reestablish the idea of honesty and trust not in the government but between normal people. Right now we are so paranoid we have nearly turned into hermits living and interacting almost solely through electronic mediums. I don't believe that the electronic mediums are the problem, but they are the crutch that allowsus to avoid the problem, CRIME. We are afraid of being robbed, beaten and murdered, those fears reinforced daily by news reports. While those reports are accurate they don't stress the point that the police were too late to stop that crime. If people are taught early to fight back and have the means to do so. Crime will quickly decrease. Yes there still will be violence, maybe even more violence. However it will be closer to a fair fight if both combatants are just as aggressive. Instead of the Predator seeking out the prey as the current society allows
