Gates complains of a CS crisis

Bill Gates writes in a Wash Post op-ed:

This issue has reached a crisis point. Computer science employment is growing by nearly 100,000 jobs annually. But at the same time studies show that there is a dramatic decline in the number of students graduating with computer science degrees. The United States provides 65,000 temporary H-1B visas each year to make up this shortfall -- not nearly enough to fill open technical positions.

I hope someone writes a rebuttal, and explains the basic laws of supply and demand. Meanwhile, see the scathing comments at the above Slashdot thread.
