Take a chill pill. You have no qualms about $50,000 SUVs, but the best cars of 1973 topped out at about seven grand, and a really nice house went for less than $80,000.
Of course, in those old days, we ancient people actually saved money until we could afford stuff and didn't run out and get ourselves nostril deep in hock.
I have watched my paycheck disappear (I'm a wellsite geologist, just in from another well) while Americans were practically cartwheeling around the gas pumps over cheap prices while drilling rigs sat rusting in the weeds.
Sooner or later, you pay for it, if the prices then had supported continued exploration we would not be in a crunch now.
A large part of this goes squarely on the heads of all the enviros who ever stopped a refinery from being built, or helped have one close down, too.
Settle down man, or your blood pressure will be rising to ridiculous levels.
