Remember, though, that if you enjoy life as a graduate student, there's nothing forcing you to become a tenure track professor and deal with all the management/politics.
And if you enjoy being a grad student, then there's little disincentive (other than opportunity cost) not to do that, learn a lot, and come out with a PhD that will make it easier and better paid to find similar work out there.
(n.b. I am assuming that one is getting a PhD in the sciences, or any field where there is reasonable amounts of funding available and one need not take loans to continue being a student.)
