Absolutely right Popa!
We paid for our kids to study in Erez Yisrael post sems and yeshivas full time for two year, expensive but a precious experience for us. Then if the boys wanted to do kollel, reality kicks in, marriage means responsibility and caring for another, not expecting them to care for you. There are many student programs that permit part time study, many kollels that understand their avreichim might do night school or external degrees. There are in Jerusalem a number of places that combine Torah learning with vocational or academic secular studies.
If my sons are old enough to marry they must be old enough to support themselves and their brides. I would be deeply ashamed if my sons actively seek support from their young brides and their families. What has happened to integrity and self respect?
