and Detroit is left without a stong middle class because liberal unions and the liberal mentality shipped all the jobs offshore!! The best people generally leave to advance their lives and the others stay hoping to leech of the government as the city descends into liberal hell.
If unions don't make better less expensive cars, just make unions illegal again!! What could be more obvious???
Liberal unions?
Unions serve the political party which serves them, not some political ideology.
It's a marriage of convenience.
Detroit is an extreme example of a one-trick union town that was crushed when Japan and Germany caught up with their post WW2 advantage and oil became an economic weapon (1973). While no longer built in Detroit, much of what we drive is still made or assembled in America despite the foreign names and designs.
Many of our aging cities lost their middle classes to their inner-ring suburbs which are themselves aging and are now losing them to newer outer-ring suburbs.
As necessary as unions once were in defending workers, they have, as all power structures seem to do, abused that power. Unions are now fiefdoms of political power wielded by union pols for their own gain often to the detriment of their members (see: Twinkies).
