I don't think your conclusion is suggested by the statistics in the article. There is a decline in enrollment, but it is heavily focused on men and white men are even slightly behind other ethnicities. This holds true even for very high household incomes where the ROI on a degree is less important than the social prestige of being in a white collar career. If college was a bad deal, you would see women opting out as well.

Not necessarily. Bad deals are generally taken due to deceptive marketing, something that drove a lot of the college applications over the last two generations. If deceptive marketing is still in play but one group, e.g. American men, is no longer being targeted...
A large generalization but in my experience women operate under the assumption that they will marry a partner that has equal or greater earning potential. Men assume that they will have to support their partner.
The other part of this is kids and biological reality. Can't imagine doing a trade or physical job while pregnant. Even after birth it took my wife a solid year or more before she was physically back to "normal".
