Lior – I believe the answer can be found in that 30 – 40 years ago, no one worried about others in Kollel. Then, the Yeshivos (Sem was barely a blip) did not promote Kollel, so those who wanted to join had to really want it and mean it (and be real). For people like that, there is only support.
However, in our times, it is promoted by Yeshivos & Sems that everyone should be in Kollel (not just those who really want it). That means support from parents, grandparents and others, raised tuition/Chessed requirements on everyone (due to those who choose to take the easy way out and are not learning 12-14 hours a day) as JFem points out, as well as (partially) an understanding of the costs of poverty on the children of the Kollel system (which is not their choice or fault). This forces/guilts others into supporting them.
To quote the Gemorah in Chaggigah (5B):
??? ???? ???? ???”? ???? ????? ??? ??? ?? ????? ????? ????? ????? ???? ??? ??? ???? ????? ????? ????? ??? ???? ?????? ?? ?????
In short, I believe what you are seeing is a backlash against “the new system”, vs. against the actual learners (who are still regularly supported).
