1. Aggressive carbon tax on all emissions
2. WPA-style investment in alternate energy and training American workers in the technologies
3. Pull out of the Middle East entirely
4. Cut all ties with Saudi Arabia
5. Set a flat tax of 10% on all earnings over $10m
6. Aggressively pursue the richest tax evaders (both private and corps)
7. Overturn Citizens United
8. Destroy "heathcare/insurance" companies
The result: A huge technological and skills boom in America, that sees everyone who wants a job getting trained and into a quality career that advances America again as a technology world leader.
Budget surpluses funding science and education programs to keep up with the blistering pace of innovation in the energy sector, and converting our old failing infrastructure to updated standards and technologies. (Everything from power generation, to bridges, to rail.)
Actual heath CARE provided at a reasonable cost by a competitive market that is focused on RESULTS, rather than government handouts. (See: Flood Insurance.)
The influence of corporate money fades quickly, due to there being less to throw around, and it being less effective at reinforcing old and outdated status quos. (Fiber internet. Campaign finance. Gerrymandering. Tax breaks/evasion. Properly funded government agencies providing proper oversight (like in aviation, tax compliance, and reporting standards), and government workers being appreciated for their diligence in spending this money wisely, rather than being told they are part of a "deep state" conspiracy for doing their jobs carefully and methodically.)
The Middle East falls apart into fiefdoms, none of which are very effective because none of them can work together without the inspiration of trillions of dollars of money to pilfer. They are completely emasculated and take three generations for a new structure to emerge from the ruins.
Russia loses ALL of its ability to influence/direct US policy, since we are no longer butting heads with them anywhere on the planet. When there is nothing to push against, it's hard to be a strong-man!
NASA has to quickly find an alternate solution to Roscosmos to get things off the planet and into space... which simply leads to more interesting construction projects in depressed/rural parts of the USA, and more people getting jobs, and more money staying within our borders.
The world economy tanks - for about 5 years - until the void of the US spending overseas is filled by dozens of smaller players who actually hold some interest in the areas in question, and spend their limited funds more wisely than the US ever had.
Which means the rise of China, India, Brazil, and (Egypt? Kenya? South Africa?) on their respective continents, and spending money/political capital on their immediate neighbors, thereby making better neighbors and stronger continental partnerships.
To achieve all of this innovation, diligence, and simple construction, will take a better-informed and more science-literate populace, which will push back the nationalist and anti-science morons to their backwoods cabins, to wallow in their own irrelevance and anti-vax filth, and slowly let those genes die out and eliminate themselves from the gene pool.
And BOOM! The world is fixed, by getting America to actually focus on, ya know, AMERICANS, and on improving our quality of life without fucking up everyone else's quality of life, and letting them get on with their ways of being.
Turns out, if you really truly pursue an aggressive "america first/americans first" policy, everyone around the world would be better off for generations.
At least, that's my plan when I become king. :-)
Glad I could help. :-)
