Again, it's just a fun conspiracy theory in my head, and no, it doesn't have to be big business. Like you realize churches have been pouring money in ads, apps, and etc. right? They're actively trying to get back all the lost memberships.

US population is growing for a combination of immigration and just slightly better birth rates than others. It's nowhere close to above-replacement levels (2.1). Just check out the population pyramid, and you can see there are less younger kids than older ones.
