1.) Flip the tables on the private central banking cartel - aka the Federal Reserve: Instead of us (the Gov't) borrowing money from the bankers at interest, they should have to borrow from the Gov't.
2.) Demilitarize the CIA and bar them access to weapons. Beat our swords into plowshares. Recommit to the principles enshrined in the constitution (e.g. no standing army), respect for human dignity, inalienable rights endowed on us by our Creator). Expand the constitution (amendments via a new constitutional convention) to included stewardship and provide personal protections in light of emerging technologies and scientific capabilities. Spread democracy by example and diplomacy.
3.) Corporations are no longer legally persons, and the profit principle should never precede respect for human dignity as enshrined in our inalienable rights. Shift to solar energy. Increase the number of property owners by creating a civilian workforce that will volunteer for two years in early adulthood to either train as militia, or serve in their communities. At the end of the two years citizens will be granted an acre or two of arable land (with a house if they choose-built by the civilian workforce) or a college education. Nationalize private resources.
