My experience has been the opposite. I've worked for large hospitals and oil and gas companies, and on any given team 50% of our senior engineers had been there over a decade.
I used to work in medical devices and hospitals, and while it's _more_ true in those industries, the numbers of developers employed is less than in Tech. In other words, it isn't the Energy or Medical industries defining the equilibrium for developers. Jumping around in medical device/hospitals also results in smaller raises than in the Tech industry. Can't speak for Oil & Gas on that part.
