There's something else going on here, though, people. I have seen parents who were truly devoted to raising their children correctly, who gave their kids a strong Traditional Catholic education, who established a good devout atmosphere at home ... STILL end up with apathetic/lukewarm kids ... and even kids who left the Church. You can put all these things in front of a soul, but at the end of the day there's the mystery of FREE WILL. You can lead the horse to water, but you can't force it to drink. And I see less and less GRACE in the world which would inspire children to embrace deeply what they have been taught.
With fewer and fewer valid Masses left in the world, the grace is drying up. And more and more I sense that the devil is completely taking over the world.
