I would push a trickle-up economics policy that pushed wealth down into the working class.
Strong tariffs to protect tech and knowledge-based work. Require ALL space industry work servicing this country to be done here. Then I’d laugh in the face of anyone who says the space industry is ever going to become obsolete, or that America is better off laying off space workers in favor of sending the work overseas and having them do something else like sit on the unemployment line. (As in, I would haul these people out on television and make fun of them on a daily basis). I’d kick start Bush’s program to go to Mars and then get to mining resources from the asteroid belt and the moon until it is economically feasible for private industry to do so.
I’d get the Government hopping on large scale development of solar farms and installing solar panels on all Government buildings, state or Federal. I’d use the old tactic of tying solar deployment to increased education or road funding. Require all solar products be made in the US.
I’d establish an honest to God Government program to reward and glorify students who excel in math and science. Put them on the same level as quarterbacks and basketballers.
Then I’d build a giant wall cordoning off the Southern United States and let them become their own nation. Except Florida. I’d need the launch platforms 'n stuff.
