I tend to agree, when universities are supplying growing numbers of a type of skilled worker, it's counter-intuitive to flood the market with foreign skilled workers.

Importing skilled workers not only floods the local market but creates a shortage in foreign markets to depress those countries abilities at effectively forming their own industry.

This is in the investors best interest as it increases their ROI, but it isn't beneficial to our local workers, nor is it beneficial to the origin countries of our imported workers.

As an immigrant working in the construction sector and I can say that the "shortage of tradesmen" is genuine and widespread, which creates an exponential increase in wages and job costs. I receive in company benefits (estimated at my cost) monthly around the same figure as my monthly income, which is likely the point when an industry is in desperate need of new workers.
