Chassidish, look the Rav’s explanation that together they sap his strength so that he does not have the koach to do aveirot.
Popa, i look at he sources you cited and I do not to what you are referring. Can you be more specific.
Toi, after the Holocaust there was an urgent need to rebuild the Tora world that was destroyed. The only way to do that was to send everyone into kollel. As the Haredi population was very small this did not cause either internal problems from guys were were not suited for this or external problems from people whjo were unwilling and/or unable to support them. Today, the Tora world is greater than ever and the Haredi population is much larger. This is causing tremendous social problems among young people who are not suited for sitting and learning all day but do not have a socially acceptable alternative. In addition, the non-Haredi population is not willing to support such a large segment of the population which is not willing to work and sources inside the Haredi sector are drying up as the older generations that worked are leaving us and those who do work are feeling the pinch because of the world financial crisis.
Thus it is now necessary to “change the diskette” and go back to the traditional system of the vast majority working and only a small elite learning full-time for life. The rabbanim understand that and thus give haskama beshetika to Haredi job-training institutions. However, the extremists, who are simply sociopaths, react with violence to any suggestion of deviation from their party line (they even stoned Rav Eliashiv because he reached a compromise on moving graves to make room for a new road).Apparently some kind ofpush will have to come from both hte grassroots Haredim who are sick of poverty and constantly borrowing from one gemach to pay another and the outside world which will give them tough love (see Shach Yoreh Deah 249:7). This will have thew added benefit of allowing Tora institutions to pay decent stipends to those few who are suited just as, lehavdil, universities give generous stipends to research fellows (and, in fact, evn one of the Meretz MKs said that those few who are suited for kollelim should receive the same as doctoral candidates).
