What happens when there are no more than 100,000 jobs available in the United States?

Question

As productivity rises, the number of workers that it takes to meet needs drops as they are replaced by machines, for physical labor, and computers, for mental labor. At some point, it seems there will simply be no more need for 90% or more of the population of the USA. What will the economy look like then? Will we all become politicians?

Answer 1

Increased productivity increases workers' marginal product of labor, which, in a competitive economy, increases wages. As wages increase, aggregate demand increases, giving new firms incentive to enter the economy and hire more workers.

Answer 2

Well, then the US will invade every other country in the world.
