There are 10 people working that can do the job there industry needs 15. How do you get the extra 5 just by increasing salaries?

That's globalization I guess, an extreme example is: would you blame a nation in poverty struggling for existence in the modern world for not attracting good techos?

As for contractors, all's fair in the free market except when contracting to government who are blind to /real/ value due to a range of bureaucratic reasons.
