First off, god bless Joshuan for his continued valiant efforts to maintain the site, often at great expense to his sanity. You're a brave soul.
As to the coomer question, it's occurring concurrently with an enormous rise in substance abuse rates (it was years ago that overdose overtook car crashes as the leading cause of death in people under 35, and the addiction epidemic in the US has only gotten much worse since), mental health issues, and suicide.
This ain't just a sex issue, on the whole pathological behaviors among the population are increasing, and I feel like the reason why is both obvious and almost completely unremediable.
We're on a trajectory we were always destined to follow, because as a species we're psychologically adapted to pursue concrete goals with more organic interests being addressed as a side effect, not through deliberate action. All through human history people, especially men, didn't have to go out looking for friends, they made them through shared pursuits like hunting or building or addressing local matters or whatever it may be, you met partners through similar means. You didn't choose to go out and get exercise, it was an integral part of daily life.
Hell, even just 11 years ago if you were, for example, a musician and you busted a guitar string or needed to rehair a violin bow previously you'd have to get up off your ass, get out of the house, and head to the music store where you'd also conveniently meet other people with shared interests. Personally I'd still do that if I had the option, but I can't, because every single one of those shops have been put out of business by more efficient means of distribution that remove frictional elements like physical effort and social connection.
And when community goes, so does people's sense of security and stability, which leads to fragile relationships and an unwillingness to create families.
So yeah, obviously people are turning to materialism and hedonism, because finding genuine fulfillment has become such a difficult process that people give up and relegate themselves to whatever shallow distractions they can find to hide from how miserable and isolated they are, especially when they have no community by which to orient themselves in terms of morals and values.
TL;DR: We've sacrificed humanity at the altar of efficiency, and now we're reaping the consequences.
I wouldn't get too nihilistic about it though. Even if the entire rest of the world sucked it doesn't mean your life personally has to.
