I think it has to do with the sudden rise of cheap pornography, cheap computer games, social media, and the lack of women who need a provider due to societal pressures and government safety nets. Before, if you wanted a girlfriend/wife, you had to get a decent job. That way the lady in your wife knew that she'd be reasonably taken care of. Now, the money you make is somewhat superflous - there are ways to get cash from the government/family members/divorce, making the man's income less important than the way you feel about the man at any particular point in time. These days, with cheap pornography and entertainment and social media, you can (somewhat) satisfy your sexual desires, your need for entertainment, and your need for social interactions with porn, video games, and social media without much monetary cost. Plus, if you missed out on the education train fairly early on, the way the job market is structured, you get fairly low wage jobs that are not intellectually fulfilling. Looking at the cost benefit analysis, if you don't have in-demand or highly paid job skills, you chocies are to sit on your butt and mooch off your parents (which is increasingly possible and fulfilling and socially acceptable), or take a low-paying boring job for 40 hours a week that will only incrementally raise your happiness level. The math seems easy to me.
