Modern Business's Second Goal is to shift all costs off onto someone else. For example, why pay to get rid of waste if business can simply dump it into a river?
Importation of high-tech labor is yet another example of this practice. Why pay (taxes) to train the locals when it is more expedient to simply bring the labor in from somewhere else? Of course that winds up costing more in the long run, but then that fits nicely with the First Goal of Modern Business: worry only about the immediate future, take the resulting money and run.
