The Demand for Jobs

Businesses won't hire workers because there is not enough demand to support them, and the public can't supply the needed demand because too many people don't have jobs.

That's what's so frustrating. If the unemployed had jobs, the demand would be there to support them. But the demand has to come first, and workers won't be hired until the demand is there.

I wonder who could provide the missing demand needed to overcome this problem?
