I wasnt born yet.Where were you working? In 1966 most HS teachers were making between $3,000 and $4,000 a year. Management Trainees at the large retailers worked 60+ hours a week for $3,600 per year. PFCs were making $80.00 a month plus three hots and a cot.
$2.50 an hour would mean $5,200.00 a year on a 40 hour workweek.
It was a way to say that folks always say”back in my day” things cost xxx lower than today, but wages were also correspondingly lower as well

..and I wasnt far off on my assesmemt of $2.50 as a guess as well then
