What is unemployment? What is the danger of mass unemployment?

Unemployment is the presence in the country of able-bodied citizens who wish to work for hire at the current level of wages, but cannot find work in their specialty or find a job at all.
The problem is that a person, even after losing his job, does not stop consuming. The state is forced to help the unemployed, but these state investments are not associated with the production of new goods and services, do not contribute to economic growth. Unemployment breeds a rise in crime.
