Joseph,
If you are going by boots on the ground, the secular and non religious seem to have won out. Frum Jews have made up less than 20% worldwide for a long time. While the vast majority of that 80% have no background, their parents and grandparenrs in Europe and elsewhere were brought up frum ( and that frumkeit in Europe was not MO, it was chassidish and charedi ) and walked away from it. The war between the Litaks and the Chassidim in Europe didn’t stop until they came to the realization that as they were fighting each other for the soul of Yiddishkeit, that soul was shrinking dramatically as they were losing more and more Yidden to the secular world.
I don’t understand why it makes a difference to you whether a person is MO, Chassidish, or Chareidi or whether one is Zionist or not. Noone is going to have their minds changed through these polemics. All it does is call alot of namecalling from both sides.If I may take the liberty of stepping into your shoes, I would direct my efforts toward outreach to the unaffiliated. Chareidut continues to grow because their large families. As Cantoresq said, the current unprecdented level of kollel participation has been fueled in the US and in Israel by the unprecedented level of wealth in the US. What happens when the current generation that is bankrolling it passes on? The downfall of Lehman and Bear Sterns did not help.
