I just read this post (about the family arrangements of Charedi women financially supporting their families so that the husband can study Torah full time) over at Domestic Felicity, which is written by an Orthodox woman in Israel. In this case, I have to agree with her assessment of the situation.
I would like to add that I do not believe that studying scripture full time is a good thing in general. We are commanded to keep the Shabbat. When we do, we devote the day to rest and matters of the spirit, including the study of Torah. The implication is that we are supposed to work the other six days of the week, especially considering Shabbat’s roots in the creation of the world. If one studies full time, then how is Shabbat set apart from the rest of the week? How is it a time of the kind of rest G-d intended?
