Say that Congress legislates gasoline price controls that sets a maximum price of $1 a gallon. As sure as night follows day, there'd be long lines and gasoline shortages, just as there were in the 1970s. For the average consumer, a $1.60 a gallon selling price and no waiting lines is a darn sight cheaper than a controlled $1 a gallon price plus searching for a gasoline station that has gas and then waiting in line. If your average purchase is 10 gallons, and if an hour or so of your time is worth more that $6, the $1.60 a gallon free market price is cheaper.
