The decline of the family has unleashed an epidemic of loneliness

Most people are alone because they don't prioritize the families they already have (parents, siblings, grandparents, cousins, etc). They graduate high school, attend college in another state, move to another city far away for work, etc. Those are choices and they carry consequences. It's not good by default to follow your dreams if the only way to follow your dreams is to be alone and isolated in a strange place. Career is only a portion of our lives and it is far from the best way to draw meaning and purpose for ourselves. It's much better to draw meaning from something that is more permanent and guaranteed, like your identity and your home, not the job you just so happen to be doing at that moment.

There are exceptions to every rule, but it should be understood that when people graduate from high school, they should pick a trade school or university that is close by, not far away. When they choose a focus/major, they should ask what jobs exist in their area, not what kinds of jobs exist in the whole world. When they graduate college, they should be looking for work near their home, not on the other side of the country. Work and career is unreliable and people fail a lot. It's not the thing you should rely on to make you happy or satisfied.

It's better to have less of a career and more of a family than less of a family and more of a career. Your career accomplishments are not as important or valuable as they seem. If you didn't do them, someone else very probably would, and you will also very probably be forgotten quickly after you retire or quit or die. But more humane pursuits like family, home, faith, and community will always be there if you invest in them.

You're in a phase of life where you could live with others, although there's no guarantee of there actually being a good opportunity near by.

I spent a chunk of my 20s living in a student housing cooperative in Ann Arbor, MI, and for the most part it was a great experience. It was big enough, and enough of the population was grad students, that it was easy to be left alone when that's what you wanted. But it was also plenty easy to find someone up for a game of chess or whatnot at pretty much any time of day.

It was also inexpensive, I still had some space of my own, and while some work was owed to keep the house running it was in practice substantially less than I spend on my own apartment with typically better results.

That's the fundamental bias of human beings. Alvin Toeffler and other authors have been banging on about that since the 60's and 70's. Vernor Vinge used to talk about this. (He helped popularize the "Singularity.")

we should take a step back and think about what is really happening

Do this, if you want to grab hold of a piece of intelligence which is invisible to the general public. This is something of a corollary to, "What you can't say."

If one has tried to talk about evolution to an anti-evolutionist, one is familiar with the depth and surprising strength of mental defenses working against evidence. If one wants to have an awareness beyond the ordinary, one has to do self analysis at this level. (While not succumbing even more to one's deeply held biases.)
