OP is saying that teaching (at primary / secondary level) was one of the few professional jobs available to women so women teachers in that era were more likely to be overqualified.
Underpaying when you have many excellent applicants may be a problem for the employees, but not for the organization. If you get used to underpaying and the supply of excellent candidates dries up, the organization has a problem.
The teachers weren't men, they were all women. Back in those days, educated women had only 2 professions available to them: nurse or schoolteacher. Anything else was basically off-limits. So schools were full of very smart women who didn't want to be a nurse and didn't have any other career opportunities.
This is what life was like for privileged white men born in the early 1950s.
Pensions were magical and housing was cheap. Powerful combo.
Additionally and probably more important it was before the takeover of the teaching academies by political activists who have turned these institutions away from a) teaching and b) subject matter into activist training camps churning out missionaries for the cause. It takes a strong character to survive there without being turned into a minion.
While the number are out there, I've always found the below story (to the best of my recollection), illustrates what life was like for someone born in the early 1950s:
- "I went to brand new schools built during the start of the baby boom. All of the teachers were excellent b/c this was before women started entering the workforce"
- "I got into an Ivy League school b/c acceptance rates were around 50% due to the Eisenhower funding getting cut so the schools needed more students to cover the lost funds"
- "I got a job from looking in the paper and started a few weeks after graduating from college"
- "Six months after I started, my boss retired at 55. So there I was at age 22 with a management role and a secretary"
I think about this story often whenever someone mentions demographics and/or the economy and why young people are spending more time living at home after college.
