I don't see the point of this post. It assumes that only men can earn money, or that lack of marriage is somehow bad for society. Those premises need to be argued for and not just assumed.
Apparently Scandinavian countries didn't get that memo that lack of marriage destroys societies; they are still some of the best places to live on the planet.
The article you linked to contradicts the point you want to make. It explicitly says that lack of marriage is bad for countries that have a sizable underclass, which is most countries.
Dalrock writes an interesting article related to Dr. Helen Smith's book the Marriage Strike. I really have to bump it up on my too rapidly growing reading list. (^_^)
