When you rewind 100 years ago to 1917, there was no DEEP then. Men and Women stayed together longer because they needed each other for survival..
This, in a nutshell. There was never large scale "deep connection". Oh sure, occasionally you hear about a couple staying together 70 years and dying in bed together holding hands at age 95. That seems to be every man's fantasy, but that is incredibly rare, but that myth is where the man-shaming comes from.
"You gonna be single forever/die a lonely old man!"
Got news for ya, there's a 99% chance you're gonna die alone anyway. Alone as in not holding hands with a woman or with your entire family at your bedside.
At least 100 years ago there was the facade of "deep connection" when marriage actually meant something. The woman actually did need men's provisioning and resources purely for survival. Men didn't "need" women as much, but a wife and children and the McMansion were the only thing that made the drudgery of 9-5 worth the 40 year struggle.
Dems and Repubs love to blame each other for unemployment, but it's not just bad economics.
This is one of the real reasons that workforce participation is so low. A lot of milennials are willingly choose to not work because a 9-5 life in and of itself isn't a worthy trade-off anymore if you're just coming home to an empty apartment or indulging in sexual "fast food" with sluts every weekend.
