Another view:
Using constitutional money (gold and silver) gasoline is much cheaper now than in the 1950's when you could buy a gallon for a silver quarter. A silver quarter is now worth over $6.00 in Federal Reserve notes. So gasoline would need to be over $6.00 to be up to 1950's prices.
Using Real Constitutional Money(Gold and Silver) gasoline is cheaper now than it was in 1960 and before! Using fiat paper its much higher.
Thanks Federal Reserve!
