When I left academia to go to the private sector, I got a 40% bump in pay, and worked at least 30% less. And I didn’t have to write grants to support my program. When I was an academic, I thought people never came back to academia from the private sector because they couldn’t. I quickly found out that it was because they’d have to be crazy to come back. I wouldn’t have returned to the university for anything less than an endowed chair. And that was NOT going to happen.
