I would have to agree with the summation of the article and also say that it is corporate Americas own fault for the situation. The sniper like focus on short term market gains has corporations cutting at the first sign of trouble it is no wonder that the talent is now charging rates to reflect this reality and scarcity.
I don't think it was a mistake, JavaScript is a very hot skill right now. Most serious (not just designer with slight JavaScript skills) JavaScript devs are making 20-30% more than their Java counterpart.
I do Objective-C, Java, and JavaScript freelancing, right now, I am booked solid with all JavaScript work. I can charge double, for JavaScript, the best rates I can get for Java.
