Another load of lies from the funny pages of the DUmp. Grocery stores have a very thin profit margin. They clear about 3 cents on a can of soup. The loss due to "shrink" from damage, expiration, theft, is enormous. Even today almost nobody is making $20.00 per hour in that industry. The regional manager of a 100 store chain might have cleared that in those days, maybe, but certainly not even the individual store managers.
I had a grocery job for a few months when I first got home from the marines in '89, waiting for school to start. I earned $5.15/hr stocking shelves. My immediate supervisor showed me her pay stub one day. She was an assistant store manager who had 18 years with the company, her pay rate was $9.50/hr.
My wife is an LPN. After nursing school, in her first job in '83 she earned $2.50/hr. Today she makes $20.35/hr, still an LPN but her pay rate did not crest the $10 mark until the late '90s.
Employed as a welder through the 90's I earned an average of $11 to $15/hr. Today in an industrial blue collar non union position I earn $16.70/hr, guys I work with who were doing similar work through the '70s tell me $5/hr was considered good money in those days.
My dad retired from the government in the early '90s as a GS15, by the mid '70s he had reached management level and believe me, he made nowhere near $20/hr then. The '70s were tough for everybody, certainly not the good old days" by any stretch. There is no way in hell this person's mother made what he claims she did at that time.
Here's a novel idea for the DUmbasses to contemplate- If you can't manage to subjugate your employer to pay you unrealistic wages with your union thuggery then open your own business, enter the market place with a product or service wrought by your own ingenuity and the sweat off yourbrow and back, hire employees, make payroll, be sure to not forget your roots and ideals though and pay them whatever they demand of you, no matter how much that may be. See how long you last.
