What were you doing?
In 1970, 15 years old, I started at $3.50 an hour doing farm work.
By 1971 was at $5 and hour, 1972, $7 an hour.
In addition to shoveling cow crap and haying, I was troubleshooting, repairing and maintaining the farm equipment.
Then went in the USAF.
In about 1974 (14 years old) I started working for my old man during the summers. He said “Well - I’d pay you what you’re worth, but I don’t think you’d work for that cheap. So how about $5 an hour?”
That is why you were pulling in $7 per hour in 1972.
