We need jobs to come back. It seems that when we have to pay more for "stuff", the country was doing good. Now other countries and machines have been taking the jobs which make the stuff cheap. But we don't have the revenue to keep up with services (but can't cut all services either). What do we do? Is it better to slap tariffs on all "cheap" countries and rake in the revenue! Isn't our only other option... default?
As for machines, we need them to MAKE jobs not take jobs, meaning that they must be used to create things that require people to finish... such as solar installation jobs. We should only go for the "best" solar, the most efficient and one that wouldn't heat up the world if deployed over a million square miles. I believe it is the 30% efficient GaAs (the kind NASA uses) in a concentrating fresnel array and LiFePO4 batteries (also machine made).
Or the solar power tower that uses molten salt for heat storage which turns a conventional steam turbine on demand. Either one is more efficient than regular flat panels that convert much of the light into infrared heat (as any dark surface does). However, flat panel should be used on roofs if their prices can come down further, since roofs are hot anyways. With just 15% efficient panels, about a million square miles would have to be installed just to power an all electric world (including EV's) using about 75% of the energy the average American uses (which is still about 3 times the total global energy use now). It would be wise to use the 30% efficient, or, at least the 20% efficient of the solar power tower.
I also believe that waste heat from power towers should be used to desalinate water...
