That’s baloney. There’s no charedi shittah of shirking responsibility. It’s the simple reality that the army is not conducive to yiras shamayim, to say the least. The same communities (i.e. chassidic groups with the same leaders) have many more people working in chutz la’aretz than in E.Y.
I have no idea what the S.L. situation is, but they don’t have such a requirement in C.L., and more people work.
That’s not what Gafne said.
