Leaving the union: All social security, Medicare, Medicaid disappear immediately. Who is fighting the U.S. Navy for the oil wells? All imports stopped. All exports stopped. The companies who drill the oil and lobby the politicians are going to choose to sell to the U.S. instead of a single entity that won't be able to pay. Now there is no fuel for vehicles.. workers aren't at the power plants, electricity failing more often than already overloaded grid they failed to maintain. It's 100+ degrees in Texas how often?
People dying, starving, traveling back in time... Do they still think they are better than the immigrants coming over to offer work and pay sales taxes?
Maybe brokering a deal to figure out immigration policies where they are processed cheaper, documented and turned into workers paid for by the the entire U.S. won't sound so bad then... Maybe they will even think assisting other countries so the people don't leave will be so bad either.
