hal,
prices (either wages or merchandise) did not increase dramatically until the Oil Embargo in the 70s).
The first big contract for the auto workers was 1968.
I had a job working in a gas station in 1968 and made 1.40 an hour.
Had a short tenure at Ford Plant in 1969,however don't recall the wages. It was enough that I could get a savings bond ($25.00-18.75) each week and still have decent money.
In '70 & 71 you could still buy a six-eight pack of soda in glass bottles for less than dollar.
Pretty sure milk and bread was still under a dollar.
