Yes. This is the key. Provider jobs have disappeared for a huge section. Also, implicit in this is that the man is the higher earner. Rage against it, but a man's attractiveness to a woman does notch up a lot of points if they are the higher earner. Basically, if you can provide. And the chances for that have gone drastically down due to a confluence of multiple economic and cultural factors.
Women who earn more also are more popular, IME. We all are familiar with the 'provider' stereotype for males, but that could be an artefact of the fact that more males were providers. That is, the fact that it happened in the past doesn't mean it is somehow necessary or inevitable (like being a hunter-gatherer, which is most of our evolutionary past).
It would be interesting to see evidence that compares the affect of wealth/income on the popularity of males and females, and also to control for social conditioning, especially of older people. Remember that part of the claim (which I am dubious of) is that it has something to do with biology.

Please stop raging against whomever you are imagining and talk with me.
