In the event of a civil war, a U.S. manufacturing system that is no longer capable of producing anything in large quantities might offer the best chance of success for the side I would want to win the war.
The gloBULList slugs that run industry want a “free” market to set prices (high hopefully) for their manufactured goods and unfettered ( i.e. no tariffs) to sell anywhere to anyone. Then paradoxically these “captains of industry” they want to fix labor rates at a low price to maximize profits. When that fixed price doesn’t attract any takers they call Americans lazy and worthless and demand importation of both skilled ( h-1B visa ) and unskilled ( wetbacks) to fulfill their slavish wet dreams. F em all.
