I was not only around, I remember how a single minimum wage job paid enough to cover rent on a brand new one bedroom apartment with a surplus sufficient to pay-off and maintain a six year-old Chevy. Think that could happen today?
1972 minimum wage was $1.60 an hour, or $256 a month. Average rent in 1972 was $165.
Leaving you with $100 to live off for a month?
But even then, let's pretend your assertion is correct. Are you accounting for the differences in quality between the 1966 Chevy, and a modern car?
How about the difference in the size of the apartment? The size of an apartment today, is much larger than an apartment in the 1970s. How about Air Conditioning?
On the wage side, are you accounting for the difference in benefits of jobs in the 1970s verses today?
I highly doubt these are apples to apples comparisons, and I have yet to meet anyone that says they wished they could go back to the 70s.
