I agree with you, but wonder — are we sitting in our ivory towers? What if we were say waiters at restaurants with spouses who are, say shop assistants and with one kid and low debts?
You lose your job in say NYC. Would you or me pack up, leave the tiny apartment with school nearby and then move on a temporary, daily paid job to pick cabbages in the mid-west? And this is a job we’d not know anything about and we’d not be physically fit enough for it (after years waiting tables or standing behind a counter).
Yes, folks did this in the 1800s and earlier, but I ask you - would you do that?
As for me it’s so far outside my situation I can give you a theoretical “if I were in that situation I’d ...” - but that’s theory.
They won’t do it BECAUSE they are making more than they were paid on unemployment so why work??
