The US pays wages that limit our ability to compete in world trade.
Not quite. China is becoming too expensive to manufacture because laborers there want higher wages for a middle-class lifestyle. Manufacturing is coming back to the US but the new factories are highly automated. When John Deere opened a new factory, they had 10,000+ applications for 800 jobs.
The non working will simply not quietly starve to death or live in want.
Or join the underground economy by doing odd jobs for cash. I had an uncle who ran a landscaping business for cash under the table, his family drew welfare benefits and never filed taxes in 30 years. Just because the jobs don't officially exist doesn't mean people won't find a way to survive through the hard times.
