That sounds like a shortage of Americans to me.
Not with official unemployment hovering at close to six percent of the work force (that alone equals around 800,000 people), and hundreds of thousands more who are unemployed but who have stopped looking.
It's an interesting paradox that the government on one hand claims it wants to increase the minimum wage to raise the standard of living, but then on the other hand they encourage illegal immigration which creates a pool of workers who will work for (or below) minimum wage. If the government stopped allowing illegals to take the available jobs, the effective minimum wage would rise on its own as shortages of workers forces employers to pay more.
Capitalism at work -- supply and demand.
