In one of my saves, the dad is a perpetual student. He's got three so far, and I only decided to have him take a few weeks off because it was distracting me from getting the teenagers through their magic training. (And he completed the Renaissance Sim aspiration, which doesn't require three degrees, but getting the degrees seemed to count for the complete three jobs so...)
Of course, he and mom have investments, magic, his scripts, her paintings, the garden and her career as Patron of the Arts to support them... (let's put it this way, when the kids head off to Uni, they're getting plenty of money to cover both Uni expenses and each of them starting off on their own once University is over.)
