"No one wants" usually includes an insufficient wage, sometimes also an issue of insufficient investment in training for skilled folks. eg if you need a doctor in 12 years you have to start more or less today.

A quick google suggests ~18% of their working age people do not have jobs, which naturally could be shifted by incentives like money or training.

(Edit, because people are confused, I'm not talking about unemployment rate, i'm talking about labor non-participation rate as a measure of people who could be enticed into the workforce with a living wage)
