Well, you could roll back globalisation and implement some form of protectionism, which is precisely what Trump has suggested.
Outside the ivory tower of economic models, it does actually make sense. If a country is severely restricted in its capacity to import (an exception being made for raw materials), and has to produce most types of goods itself, then the economy tends to approach something like full employment. Meaning that although overall GDP is not maximised, but everyone has a job, and every industrial sector thrives.
An additional advantage of protectionism is that it would put the brakes on global economic growth, which is the major driver of climate change and ecosystem destruction, but without the side effect of mass unemployment which would be inevitable if free trade remained operative.
