Yup, people follow incentives. I was friends with someone in college who majored in chemistry and could have easily gotten into a good PhD program or gone right into industry. She chose instead to teach high school chemistry and did a fantastic job until she burned out 3 years later. The work load was enormous, the pay was shit, many of the kids didn't want to be there, and the goals of her school administration were completely decoupled from the general purpose of teaching. She is now in industry making much more money and living a much better lifestyle.
