I'm single by choice, due to the availability of single women my age without issues (for lack of a better word).

What a garbled way to put this, but it is of a piece with the rest of his reasoning.

Women in his age range who are financially secure (and due to the inequities of the economy, there are far, far fewer of them than women who are not) don't need to put up with his brand of self-righteousness judginess; younger women who aren't looking for a sugar daddy don't need to put up with it, either. Afraid he's SOL.
