I don't think anyone studying this seriously is making that argument or even trying to slyly imply it.
I think it breaks down like this:
We know "lots of single men" correlates with many indicators that are, broadly, "bad for society".
What is driving this change? What can we about it? The "what can we do about it?" is focused, again broadly, on "fixing men" or "fixing the incentives for men" or "fixing the opportunities for men."
No one is proposing, "Hey women, you better start marrying these unattractive layabouts or else society will collapse and you'll be living in dystopia...".
