We have been going off topic, but I know a bit about both lakewood and modox day schools (having relatives in faculty and administrative positions at both). Aside for the differences mentioned above, which are significant, one thing that I'd like to point out is secular studies teachers are more expensive than judaic studies teachers. Most modox schools pay the same for both, but the wages are similar to what public school teachers get paid (50k-70k) as opposed to half that. Modox teachers also are more often full time and receiving benefits (again, more similar to public school). My point is that the wage difference isn't just they want to pay the teachers a living wage, it's also that the market for what they prioritize demands higher wages (or you'll get crappy teachers).
