Outside of medical, education, and government (local, state, federal), I cannot think of one safe field other than service. Can a country survive on service jobs? I hear constantly on TV that the unemployed are being "retrained." Retrained for what??? If the normal rate of unemployment in good times is 5%, where, pray tell, are the other 95% going to work?
My aunt retired from a shoe factory after 30 years. In the late 1970s she would be temporarily laid off at times because of the Italian shoe competition. She was compensated by our government then. Nobody seemed upset until "down-sizing" hit the elite jobs, tech jobs such as soft-ware engineers, etc. I'm not a protectionist but, come on, how about a little fair play for our jobs in the world market. Our politicians don't require other countries to provide benefits, pollution controls, or simply humane working conditions.
This whole job loss began decades ago and will only get worse. Factor in all the millions of uneducated immigrants coming in--the bottom rung is going to be very crowded. This may not be a subject that we want to discuss; it is very emotional.
