There is absolutely no shortage of workers at the lower end of the skills range, there is however a big monetary issue at play that prevents people from hiring people locally in a number of different situations. On top of this there are regulatory and taxation imbalances that make certain industries unable to compete with foreign firms that don't have those issues. The problems are frequently the price of labor not the raw availability of labor, people certainly will take on jobs if there is enough pay to make those jobs worth taking.
