I think that what has happened is that rather than being regarded as the form of tzedakah that it truly is, this unqualified total financial support is looked upon as an entitlement. No one is entitled to be supported by anyone on an ongoing basis, unless there are mitigating circumstances, i.e, the person is not able bodied or ill in some other way. Hashem expects us to earn a living. If not, there would absolutely no need for any halachos in the Torah that pertain to parnassah, or of working the land in E”Y. Does the Gemorah not say that a man who has not taught his son a trade, has taught him to be a thief (or something like that)?
Some men are such iluyim that they should ONLY be immersed in Torah (and they can earn parnassah of some type from that also, by teaching Torah to others). Most frum men do not fit into the iluy category, and they should be doing both. They might WANT to only sit and learn (why not, wouldn’t anyone prefer to do something he finds meaningful and enjoyable all day, rather than punch a time clock?), but that is impractical, considering that mouths have to be fed, diapers have to be changed, tuition has to be paid. It is unfair to be angry at someone for pointing that out, IMO. And it is equally unfair to expect people who are NOT immersed in Torah or even frum, to be blindly accepting of those who are, when they do not understand the importance of learning. If some of those of us who are frum feel that the yungerleit should not expect to be blindly supported forever without their earning a living or without concretely giving back to the country out of appreciation for the support they do get, how could the non-frum world ever be expected to accept that? And that is the crux of why the Israeli government is giving the yeshivah boys so much grief now. There are at least two sides to every story, and if we are to be fair, it would be a good thing to try to reasonably understand the emotions that are involved here now.
