Baloney, at least to a point.  It is subtraction, not addition, at work. Kids with are rejecting a straw-man Christianity, a sick parody Mass, and a trite caricature of Christ.  The flimsiest and stupidest arguments for atheism or (sometimes) megachurch jive-Protestantism pull them away when they're old enough to be exposed to them, because they don't know what the Church believes let alone why it believes what it does.  Faith without reason is stupid and flimsy and bad, sentimentalist, unchallenging reason-free catechesis (e.g. C.C.D. programs) leaves the youth defenseless.  It's the same as it was 20-30 years ago and often with the same people in charge.

But one could also say that faith isn't being "caught" from our liturgical prayer in most places.  And conversely the "reform of the reform"--offering, at long last, the Ordinary Form in the way Vatican II actually specified--so opposed by many of the blue-hairs has a marked tendency to make disciples out of mere cultural Catholics.
