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.

Forgot to add, enforce DVORAK keyboards.
