I was teaching school in 1972 and moved my family to Alabama. I gave strong thought o doing the Nanny thing. As a male with a Masters degree, I had a couple of good options to earn 15,000 annual. Teaching Fairfax, VA only paid 10,000 for a Masters degreed teacher.
15k in Alabama in 72 was pretty good money. That’s back when a buck was a buck.
