Plus we are more efficient. You don’t need as many people to manufacture things or grow our food. you don’t need telephone operators, secretaries, travel agents, people to man toll booths or subway stations, etc.
Of course, none of the financial benefits of this increased efficiency have gone to the masses. The billionaires just gained even more wealth.
Our productivity has gone up, but people really don’t feel it because everything has gotten so much more expensive.
In an economy, where there is increased, efficiency one would expect lower prices. If there is no longer a need for someone to hand out tokens in the subway, why does it cost more to ride the train? If we don’t need people to collect tolls, why has the toll increased? If the United States is energy independent, why do gasoline and utilities cost so much more?
