DaMoshe: Chareidi Yeshivos, despite having a significantly lower tuition than MO schools (which are more often than not co-ed), provide a far far superior Limudei Kodesh Torah education than any MO school. Everyone sees and knows this very clearly and unambiguously. The extra money put into MO schools goes towards secular studies.
And, still, 50% of the MO students end up OTD; a statistic coming directly from eminent MO Rabbi Steven Pruzansky of Teaneck. In the Chareidi world, the OTD rate is in the 1% ballpark.
It is clear who is doing things right — and who is doing things wrong.
