There are books on this phenomenon. Part of what they say is now men have access to their basic needs with out needing to work as much. Entertainment is abundant and relatively cheap and sex isn't tied to marriage. You can lounge around and be if not exactly satisfied, at least not terrible wanting for stuff. Of course these guys are screwed when it comes to retirement.
Shortly before meeting m'lady, I'd nearly paid off the house and otherwise driven my expenses to near zero. The prospect of withdrawing from the system ("going Galt") was becoming a realistic option; grow much/most of my food (as my folks had growing up), find a mundane job in walking/biking distance (notable as I lived in the country), and spend my time writing what software I wanted and puttering in a back-to-basic…

In other words, one of the easiest ways to be poor is to have a dad who isn't (can't or won't) fulfilling his responsibilities. Men and women who are fertile and sexually active need to be able to care for a child for eighteen years. Yes, birth control, please. But there are millions of single moms out that came from somewhere.
Additionally, someone needs to pay for current social security retirees, poverty programs, etc. And if you aren't having kids, someone else's kids will be paying for both their social security checks and yours.
I say all that not to be judgmental, but to point out that the numbers don't add up for men to just live the minimalist lifestyle free of guilt. Like I said, that's possible, but you'd literally have to live (and die!) off the grid while somehow caring for orphans, veterans, and windows at the same time (lifestyle choices don't count).
