The lack of price controls is the one thing different between today and 1973.
I do remember also:
Cities were in REALLY lousy shape, many nearly completely dilapidated and run down. Most cities, roads and infrastructure is far better off today than it was then.
Cars were simply horrendous, and on their way to being hideously horrendous.
People were wearing things like plaid elephant bell bottoms, and double-knit clothes were appearing on the scenes.
There was a general air of depression and disrepair.
However, the music was FAR better.
