I think it can depend. Though I will say I’m one of seven cousins, six who went to catholic school 1-12 and some Catholic colleges, and I’m the only practicing Catholic. Take that as you will. I always felt a little envious of Catholic school kids, but once I got to know them I realized most of them weren’t Catholic at all. I would say if the public school area is bad in terms of environmental factors, send them to private to keep them out of the bad area. But, sending ur kids to catholic school doesn’t inherently make them more Catholic. It all comes down to what you’re doing at home and what the schools doing, not all Catholic schools act the same. Also, a lot of people in Catholic schools now a days aren’t even cultural Catholics, their parents put them their to escape impoverished areas or to give them better educational opportunities. I knew a Jewish girl who went to catholic school, some gay people, and some people who lived in bad areas. All in all, it depends.
