Well, consulting salaries are usually significantly higher than industry salaries. So it is actually the opposite. People move out of consulting because of the stressful hours and the up-or-out culture. Additionally, as you progress, the work goes from IC to project management then to client management (as a principal) then to sales when you become a partner. They tend to make less money when moving to industry (not always) and work fewer hours, and travel less too.
