However i find this arguable since i believe there are many more higher wage jobs that those listed above. Many non degree jobs that are short of supply will require higher labour costs, so certain cities or states depending
on scarcity of labour could have a shortage in certain industries therefore causing upward pressures which may be favourable to people looking to go into the field for a period of time.
