Whenever there are government mandated licenses that one needs to receive in order to work there will always be a surplus of unemployed nurses or really any occupation that is licensed. Its the natural effect of such practices. Employers have direct decision making on hiring in their business, but ends where their sphere of influence ends. Meanwhile, a governmental license blankets the entire market and makes it extremely hard to find productive work if one does not have the "privilege". One may argue that these restrictions and regulations are necessary, but the natural by product is a shortage of workers compared to what would have been.
