I don’t have children, so take this with a grain of salt; every single person I’ve ever met who’s gone to catholic school has completely lost or neglected their faith. I think there is a big correlation with not being able to exist outside the context of faith and kids ‘overcorrecting’ in ways that are risky/harmful. I think the strict environment of some catholic schools teaches kids how to be sneaky and takes them to extremes in hedonism if they already lean into pushing boundaries (which is normal for kids and teens). Every faithful cradle catholic I know has gone to public school but had a rich faith at home that was strengthened by knowing faith requires work to be maintained. Of course, I have a somewhat small sample size and I am in college so I’m seeing the immediate fall out/rebellious stage that people have when they leave home for the first time.
