My folks were never "high income" workers, Dad at a local car dealership, and Mom a secretary. They gave 10% of every penny they earned to the Lord. Dad bought a new car every three or four years, trading the old one in on the deal. He worked for the contractor to build our new house in 1960, and financed the deal with a GI loan.
My sis and I never lacked for anything including some pretty cool vacations growing up. We had to earn our allowances, starting at about the age of eight or nine, and both of us had jobs of some kind by the time we were teens.
Both folks retired when they were 62, and started taking cruises around the world. --Several months long stays in New Zealand and Australia, Panama, time share in Maui -- it was pretty amazing to me, since I knew how they made their money and how much it wasn't.
Dad and I were fishing one day, and I asked him what he thought was the biggest factor on how comfortable they'd always been. He said, "When I picked my woman, I picked the right one, and I made damned sure that we stayed together. When we decided to tithe to the church, there just never seemed to be a problem with money. And we were very lucky."
They both lived into their nineties, and were indeed very lucky and blessed. Their son was a problem for quite awhile, but even he managed to pull it up and straighten out in time for them to appreciate it.
You might say that those were different times, -- and they were, but there were still plenty of folks who made hash of those times and never had two nickels to rub together. Financial stupidity and poor life management has always existed, and always will. I'd say those figures on the State Income Chart are crazy high, and that it says a lot about how "uneconomical" most folks are living today. jd
