I'd probably group them all under the umbrella of social connections failing, which I'd consider one of the biggest issues of US society today.
Which is to say their doesn't seem to be any indication that "marriage is failing" i.e. there are less people in marriages. It's also notable that the rate of cohabitation has tripled over the last 20 years[2] (included because it's a worthwhile proxy for things which are long term relationships but might not be recognized as marriages).
Where I can point to fertility rates across the Western world falling to below replacement and say "yeah we've got a problem", the notable thing is that it seems thoroughly uncorrelated with people being in long term relationships. People might not have time for friends, but there are more committed relationships around then at any time in history - by the numbers.

I suspect that accounts for a decent chunk of people not getting married, but still being in long-term relationships unless there's some evidence these are substantially different types of relationships (i.e. not intimate).
This probably understates things, if anything; as you get older, you're more likely to get married, and America's population has been aging.
Pew data shows that marriage is down 14% since 1990.

I have to wonder if people, and newer generations in particular, just fucking suck at socializing.
Humanity has very literally never had it easier to communicate and socialize, and yet somehow the vast majority consider themselves isolated.
It's easier to socialize when you are physically beside someone.
There are less kids playing in the street. They are no arcades.
As a parent you must bring your child to other children. You must encourage or mandate extracurricular activities.
We are not a society where children are naturally surrounded by other children in their 0-4 years.
We are not a society where adults are naturally surrounded by similiar adults outside of the in office work space.
Its a matter of proximity and what is the default state.
That's shocking to hear. We live out in the sticks, about 25 minutes from the nearest town (of ~10k people) and we make sure our kids get some social time a couple of times every week. From homeschool coop groups to random meet ups/activities planned by parents via Facebook to farmer's markets, library/museum trips, churches, parks, visiting neighbors... seems like my kids are always doing something which seems to help them socialize. I think it would be sad if they just stayed home all the time. I suppose being in a traditional marriage where I work and the wife raises the kids helps contribute to this being able to happen.
All of these other than visiting neighbors are exactly the things nightowl means when saying they're not naturally surrounded. You're having to arrange the homeschool co-op, you're arranging playdates on Facebook, you're taking them to the famers markets and museum trips. You're facilitating them going to these places, probably by way of car.
Comparatively, growing up most of my childhood days other than school and one weekly extracurricular most of my time was just naturally playing with the kids in the neighborhood. We'd all just play in each other's yards, we would just go to the playground ourselves, etc. These days you would have CPS called.
Saying these people fail because they don't get married feels like imposing a certain viewpoint on others. I'd say it's a problem if they want to get married and can't find a partner. Incels are a problem. People who are happy with their life aren't.
This notion that two people being in a long term relationship can somehow suffer systemic failure or attack is bizzare.
No objection re: children though. We've done an absolute number there via cost of living.
