There are also plenty of cultures with family values not rooted in religion.

Basically all forms of outward focused, community or geographic based groups seem to have been on a downward trend for decades in favor of hyperreal, inward-focused online spaces.

Although I agree with the sentiment, I think the problem is what replaced it, not that they were replaced. Religious belief has been replaced by a quasi-religion revolving around clipling autodetermination and aggrandizement.

I don't think people suffer from not having faith in some god nowadays, I think they suffer for not having faith, period. I see people around me prefering to live in known discomfort, than choosing to "roll the dice". Religion played the role of teaching people not everything that happens to them is in their control, and comforting them that it would all turn out well. What we have nowadays is the awfuly debilitating belief that everything that happens in your life is your own doing, and that unless there's evidence thigns will work out, there's no reason to believe they will.

I personally see the risk-adversity this philosophy leads to everywhere. I see it in people prefering apps over potentially making a fools of themselves, or "risking it" with a stranger. I see it in people who want leave jobs or living situations but fail to take the leap. I see it in people strugging with even small decisions, obsessing over reading reviews for everything, refusing to commit in relationships.

Religion also gave you a certain peace of mind concerning your purpose in life, and assured you you could be perfectly content with little. In fact it assures you can be more "successful" at life than people who achieve great wealth or fame, since in religion success is measured by, say, devotion, acts of service, building a family, or other means instead.

This can be replaced by positive philosophies that focus people in the prusuit of eudaimonia, but instead have been replaced by reverence to aggrandizement and too often hedonism. The goal too often becomes fame, money, status, or, again, control, both out of fear your life might not be determined by you solely, and for the pursue of vain pleasures.

I see this as a product of an obsessive reverence to libertarian capitalism. Overall, it works very well in its favour. Convincing people the course of their lives depends soley on their own decisions is ingraining reverence for individualism and rejection for collectivism. The pursuit of wealth and status is good for the economy; when people are truly happy with the small things in life, they tend to buy less. I'm not saying libertarian capitalism lead to this philosophy, or that this philosophy lead to libertarian capitalism; I think they go hand-in-hand, and as one grows so does the other.

In the days of subsistence farming, a child was an additional free worker. Once we mechanized farming, we went from 50% subsistence farming to 1%. Children moved from the profit-center column to the cost-center column.

Medicine improvements and government policies have reduced child mortality. Mothers no longer need to conceive 12 kids to ensure that 4 live to adulthood. Each birth is a much higher resource cost and a much larger responsibility than in generations past.

The gratifying life of being a stay-at-home mom to 18 kids only works so long as the father keeps the money rolling in and doesn’t decide to abandon the family (this happened to an aunt of mine). The modern changes to family structure didn’t happen out of the blue — they were a response to inadequate protections and violations of freedoms that people had at the time. You might consider educating yourself on your blind spots about the topic.

Churches are eating themselves. People aren’t “moving away from God” so much as seeing the churches as liars. Christianity is full of lies: many small, some big. The more that people are exposed to others with different perspectives, more education, and better ways to communicate complicated topics, the more likely people are to leave a church that lies to them. Churches which have been outed for covering up child sex abuse have seen outflows. Bad policies made it more likely that the child sex abuse would happen. Further bad policies prevented the abuser to go free without prosecution. Even further bad policies have allowed the internal investigations/reviews to be quietly ignored.

Ultimately small churches have empty pews because they aren’t entertaining. MegaChurches / televangelists based in Orange County, Dallas, Houston are pulling in members while small town churches close due to lack of membership. Churchgoers tend to care more about being engaged in the showmanship of the leader than the common benefits of keeping a community alive.

The other functions that churches serve (community service, reminders of purpose) are being replaced by the free market of ideas. Some churches are turning the pulpit into a political campaign. Many secular non-profits are taking up the slack of dying community churches by doing a slice of the same work without the lies, sex abuse, coercion, and threats of damnation.

Then there are completely unrelated changes in society. More people care more about having pets (dogs, cats) than children. Values change as society changes. Companies get far better at marketing than individuals get better at resisting marketing. Drugs, gambling, sex/porn, outrage / attention economy, etc have all been turbocharged via capitalism.

The values of the average person have changed a lot. It doesn’t make sense to cling to the old institutions if they don’t meet the people where they are.
