In reply to Chris Amstutz:
I tend to be an optimist about having new folks enter the world of process automation. I was in college in the early 1980s. At that time, the oil business was booming. Starting salaries for petroleum engineers were much higher than for any other engineering discipline. This salary differential spurred more engineering students to become petroleum engineers.
When the boom busted later in the 1980s, the starting salaries normalized among the various engineering disciplines. Many petroleum engineers moved into other industries and learned new skills in areas such as process control and instrumentation.
As high school age kids begin to think about college, I think that starting salaries remain a consideration in their selection process, as it did a generation ago.
And, as shortages develop, salaries will rise and smart people will join our process automation ranks.
Did I mention that I'm an optimist? ;-)
