It's much easier to take apart a system than put it together. Hell even nietzsche talked about these problems coming up, as a result of losing religious institutions that maintain societies cohesiveness. He said God is dead, and we killed him. He asked what great festivals will we have to invent to make ourselves worthy of such a great task? Well we didn't invent any festivals or institutions to replace the church. People just aren't interested in that. So there is no secular Sunday service where you meet and socialize with your community every week

Anecdotally, I'm part of a tightly knit religious community and these problems are much less common. Even the nerdy awkward kids all have friends, why does it matter that they're awkward when they're still good people? But I rarely saw that sort of thinking in public school. It was as much a free for all as adult society and there were kids I saw go without friends from middle school to high school graduation because no one wanted to stomach their being awkward.

But often when I bring this up and rather than help the kids, people would usually try to convince me that my religion doesn't have any value. There's no interest in actually making things better, just taking things apart

Yup, killing the family unit is a shot still heard.

Degrading social care systems and social mobility is actually to blame for this. This is what OP is missing in his/her rant.
