The comments that were posted to my previous remarks are so important, that I decided to respond to them in a post of their own.
1) Malnutrition etc.- It is an open secret among welfare workers and therapists that 'holy poverty' leads to hunger, malnutrition, spousal and child abuse, abandonment, divorce, and sarvanut. These phenomena are not confined to the Baal Teshuvah population (as many FFB Haredim would like to believe). The tip of the iceberg has been addressed by Haredi columnist, Tali Farkas, on YNET.
(It's also not irrelevant to mention that the fantasy that everyone should be a Gadol ba-Torah and only learn Gemara is a central factor in the ever increasing phenomenon of Juvenile Delinquency, crime, abuse and abandonment of Judaism by Haredi men and women.)
2) At the same time, Haredim have perfected the art of exploiting the system (not, per se, contemnable). In the process, the community has developed an attitude of entitlement that is absolutely contemnable. The attitude is: You owe me a living and have to work to provide it.
3) It was observed that the statistics are questionable, because many Arabs and Haredim work 'off the books.' The statistics are easily available here. (Thanks to Religion and State for the link.) Not a few Haredim work off the books. However, I fail to see how that helps. They don't declare the income and they do absolutely nothing to contribute to the country. On the contrary, they both work off the books and take government and Kollel stipends. In brief, they're guilty of theft. Such people are halakhically רשעים and disqualified to serve as witnesses.
What should be done? I'm afraid that, given the doctrinal inflexibility of the Haredi leadership, the only thing to do is to drastically limit support of Kollelim, and largely stop that support after a certain age. Further support can be provided promising students, and those who commit to enter education (with education degrees). At the same time, the government will have to create the scenarios to train Kollel students in whatever field they want.
There will be incredible upheavals over this. However, if the abject failure of the rabbinic ban on the internet is any indication, the effort will ultimately succeed ויגדיל תורנה ויאדירה.
