Dying alone after a happy life is one thing, dying after decades of hell with a bad partner is another, and yet another to pay someone you hate until you die, like many men in California do.
Presumably it's a reference to California not having a statutory limitation on the time horizon for alimony payments (and also allowing for courts to reopen alimony decisions years later) after a marriage of more than 10 years is dissolved.
I think he meant a large number of divorced males in California although relatively speaking, California has one of the lower rates of divorce among all states, with the highest in the South.
