50 years ago gas was about 16 cents a gallon where I was growing up. A nice new car was about $3500 and a 1300 sq ft house on a quarter acre lot was about $12,000. So you may be about right with your statement.
At 2.70 gas is cheaper than it was fifty years ago.
I have posted this previously. We can gauge the destruction of the dollar by silver coinage valuation.
I like
War Nickels for comparison.
Gasoline in 1945 was ¢0.21 per gallon or 4.2 War Nickels. Today, War Nickels are worth ¢.85 in metal weight alone. 4.2 nickels will buy you 1.32 gallons of gasoline.
Indeed gas is cheaper and would be even more affordable without fuel taxes that line special interest pockets rather than infrastructure maintenance.
The frightening thing is how debased the dollar is. Obama committed many crimes with the deep state, however the greatest may have been the Keynesian 10 trillion dollar debasement of our currency.
