My husband worked 8 hours a day and 254 days a year. Not surprising that he made more than a teacher.
I was a teacher and taught from K - community college over four+ decades. My teacher friends NEVER stopped complaining, ever.
Now they complain that their retirement isn't enough.
I went ahead and got my Master's degree and, consequently made MUCH more than they did and have double their retirement.
They COULD have gone the same route as I did, because we ALL had to continue our education over the years. They took "fun" classes and I took the courses for a Master's. It's not rocket science.
So you are suggesting that the 60 hour work-week mentioned might have been an exaggeration. (DUH!!!)
