>Look at it this way: no one is complaining about the lack of girls in the blue collar industry.

Actually, I remember hearing quite a bit of complaining back when I was in middle and high school. However, it occurred alongside a concerted effort by the Province of Ontario to increase the supply of tradespeople at a time when there was a shortage of 'qualified' (read: certified by provincial licensing bodies) ones in Ontario, which led to exorbitant prices on associated goods and services. So, to be cynical, this could be much more about price correction than anything else.
