Finally, a proposal to change everything.
First of all, the USFG must take a count of every dollar in circulation and keep count of every dollar printed afterward. At the push of a button the government should be able to invalidate any bill. All dollars leaving port must be required to pass through customs/documentation and the state should be able to demand audits at any time to track the whereabouts of dollars suspected to be missing from the country.
If cash is gone because those treacherous demon-possessed bastards fled the country with it, we could push the button and make their stolen loot worth nothing. That dollar could be re-printed immediately and re-enter circulation here at the government's discretion. Obviously there would be enough rule of law that it couldn't just randomly happen to any citizen but only as a consequence of criminal forfeiture. Fear of exchanging a valuable foreign currency or asset for possibly worthless money would force external parties doing business with these corporate thieves ponder long and hard before making a deal and consult USFG resources to make sure it was legal.
Obviously this would make it a lot more difficult for America to do business with the world. But that's actually the point.
Second, radically revise the tax code so the USFG can tax nonliquid assets that have traditionally been very hard to tax. Nobody evades our tax regime. The state and the citizenry it represents will take its fair share of the sovereign wealth no matter what.
Third, we should begin to shrink the national debt, even if it means several years of austerity. Once it's down to 80% GDP, we can safely proceed with:
Fourth (optional), block most imports. Require most items that Americans consume to be made in America. We'd become a closed economy and aim for self-sufficiency.
Fifth (optional), because this would make life drastically harder, a hundred other reforms in other areas would be needed. The entire available workforce would have to be mobilized like nothing seen since the end of WWII. We'd build our own solar panels, recycle our huge (currently unwanted) reserve of wasted plastic to produce carbon fuels to sustain powered industry, extract uranium from the oceans, and find ways to conserve electric power at all times. America, unlike most countries, is geographically massive, blessed with an abundance of diverse natural resources, has a varied climate ranging from northernmost Alaska to the tip of Florida, a well-educated workforce and a large industrial/infrastructure base to start with. The UK or Japan certainly couldn't pull this off but maybe we could. America's has always been in a unique and enviable position when it comes to this.
Affordable housing and manufacturing jobs would be plentiful. One's private speech, beliefs, religion race or sexual orientation/gender identity would have no bearing on one's ability to find or keep work as long as one's conduct on the job was respectable. Measures of economy would have to be restructured but after adjusting for inflation each person would be paid as handsome a wage as could be sustained. Jobs would be plentiful and management positions would be too. Home design would be optimized for cost and ergonomics.
In the new economy employers would seek out workers and not always the other way around. They'd come to you and offer you intensive training to perform whatever task they needed performed. Approaches to technical instruction would be reformed; as the sum of knowledge continues to grow while human brain capacity remains the same, it's not sustainable to teach people more and more each generation. Instead, they'd be taught to effectively wield the evolving tools of their trade, each having been built upon prior industry knowledge that the wielder doesn't need to know much about. If one person with this level of knowledge wasn't enough, others could be taught to specialize, which would create more jobs.
Sixth, put limits on automation. Machines must always remain tools, not workers themselves. This cap will have awkward implications at times but if we're not competing with the world then we can afford inefficiencies.
Seventh, acknowledge that the US will suddenly become very weak compared to the rest of the world. With the rise of China and India we were never going to remain #1 and so long as we maintain a credible WMD deterrent, along with the political/moral will to use it, we needn't fear that outcome. As long as the average citizen has a better deal and a brighter future (even with some sacrifices), maybe it'll be worth it.
