Things have changed significantly in the past few years. It's had been difficult for me to wrap my head around why the tech market appears to be so different now than it was 5 years ago, until I recalled the supply/demand conversation. Many of our talented Engineers have moved on, and management hasn't been able to replace them. For a while we've been struggling with staffing. High quality, enthusiastic, eager to learn technicians have been few and far between. This article and the salaries that our Engineers have been leaving for seems to confirm the supply/demand theory. Perhaps the demand brought to light in the article will spark more tech career interest, and perhaps tech staffing will become slightly easier for companies that are unable to invest too highly in IT wages.
