Youve never seen a shortage because you havent lived long enough or your just to dim to have noticed.
In the late 60s-early 70s they had shortages of police and firemen and public employees in general in alot of major cities. BECAUSE THE PAY WAS WAAAY TO LOW, grasp that right winger who thinks everyone should be a lackey for the rich and work for free.
It was until police pay went up considerably before the shortages went away.
Do you have anything credible to support your dimwitted claim; or is this another "because you say so"?
