My grandfather was tenured, published voraciously up until he retired at 73, and was sorely disappointed when I chose not to follow in his footsteps and go into academia. Why? Primarily because I had to hear him gripe about how poorly the school administration treated him and his colleagues, culminating in him having to sue the university several times for the same reasons (and him winning every time in arbitration- he basically tripled his retirement savings).

I have a lot of respect for academics, but the culture around the administration of higher learning is putrid.
