The small town factory/mill/plant - a manufacturing entity - provided secure employment and chances for advancement for unskilled millions but NAFTA and the like sent America's industry out of the country leaving little but the service industry to employ the country's young and the service industry is low pay, little chance for advancement and no job security. Yes, there are 'made in America' industries but most are highly mechanized requiring few human hands.
20 years of that has brought us to today where there is a minuscule number of obscenely wealthy individuals, a slightly larger group of financially secure and a massive number of destitute or near so. The wealthy, as well as our own government, work philanthropically to help the disenfranchised in countries all over the world but ignore our own citizens. While we 're-build' abroad, our own nation crumbles.
