“Can someone please quote a phrase in the torah where it says to sit and learn all day and mooch off people? “
There may not be a pasuk, but I think that it is in our own self-interest to have people learning day and night. We need people who are going to become talmidei chachomim. We need people who are going to be experts in halacha to answer shailos. We will need people who can give us a Torah perspective on events in the world. As such, I think it is in our own self-interest to have people learning all day and preparing to fill these roles.
However, I also believe that the current kollel paradigm is not sustainable. Nor do I think that it is good for the community or the individuals involved. I believe that kollels should have strict entrance requirements, so that only a certain percentage will remain. They should (like any advanced student) be required to prove their competency from time to time and maintain a sufficient level of scholarship (must like you must maintain a good GPA to remain in a graduate program).
Everyone else should go to work and support those who are learning, as they, too, have an interest in the next generation of leaders of k’lal yisroel. As they also have a requirement to learn, I think the yeshivas should have an open enrollment policy for night/weekend sedarim, allowing anyone who want to learn to come in and learn during those periods.
