Taking these four elements together, we begin to see a reasonably 
clear picture of the economic mechanics of the American empire. Imperial
 power backstops cheap imports and the ability to run endless budget and
 trade deficits. Various countries absolutely have been brutally 
subjugated to protect the profits of American businesses over the years.
 Others have been trapped in debt peonage by U.S.-backed IMF austerity 
programs, while the grinding poverty of the Global South effectively 
protects America’s disproportionate share of world resources.
But here’s the main point: The downsides, even for Americans, are far
 more numerous. American prosperity—by which I mean the standard of 
living of typical Americans—in no way depends on this empire, 
and the broad American public is in no way the major beneficiary of the 
system it promulgates. Instead, it is run in the interests of a tiny 
class of business executives, investors, and military contractors. The 
American people are routinely victimized by the same ruthless bankers 
and pharmaceutical executives running riot in the Global South.
And this leads to an important political conclusion. It would be very
 possible to reform the world economic structure to allow poorer 
countries to build up their prosperity without truly harming the broad 
American public. Above all, the U.S. economy would have to be become 
drastically more efficient—which should be possible given technological 
developments. Carbon- and pollution-spewing coal and natural gas power 
plants could be replaced with renewables (which are now 
price-competitive with fossil fuels) and nuclear power. Gas-guzzling 
SUVs could be replaced with smaller electric cars. Heating and cooling 
for buildings could be made drastically more efficient with electric 
heat pumps and improved insulation. And all without sacrificing 
growth—one model suggests a green U.S. economy could be 158 percent 
larger by 2050.
