Have you priced in cost of keeping your old one?

My speculation is that teenagers react so vile to adults trying to fit in partially as a unwittingly defensive mechanism. Teenagers have some social skills, but not all and thus having separate youth culture provides spaces for learning - adults trying to fit in are possible OP in those spaces and keeping out adults altogether might help with abuse prevention as well.

I don’t really know how to test or research this speculation though.
