That must explain all the young people I run into in various parishes.

That explains a Russian Orthodox parish I recently visited that was chock-a-block with young couples and teenagers.

These problems are self-correcting. As John Hobson has recently been pointing out, the children of critics Church wind up outside it, and the children - and there are more of them - of orthodox Catholics, Orthodox, et al stick around and repopulate.

Voila! Problem solved.
