Toi: It goes back to my original post on the thread. If the Kollel Bochrim were using their time during Bain HaZmanim like the Gedolim suggest (as some, but not most, Kollel Yugelight do), then they would have no need to worry about the Medinah drafting them, and the Baal Habatim would support them as well. No one begrudges someone like Rav Chaim who learns all day every day from not joining the army! (Obviously, besides for age).
As my Rov has told me: There is no shortage of money in Klal Yisroel. People would rather spend it on something that produces. If there were more Yissachars, then the Zevulans out there already would be willing to support.
