Cool solutions to our problems in the USA:

Education: Shift public spending from military and defense to space exploration and research and development. This would create demand for engineers and scientists within the USA and drive many other lower level jobs as well. Our current focus on combat and war is bankrupting us while we have other more important issues at home.

Oil, Gas and Global Warming: Huge tax on gasoline. This would initially hurt everyone, especially those near the bottom of the pay grade but it would solve the issues over the longer term. Smaller, more efficient cars would actually make sense to purchase, bike lanes would be used more, public transit would actually be used by normal people. Ten years out, dependence on oil has decreased while more efficient cars have become a reality and people are spending less on gas than they were ten years before.
