I am not going to add much to the posters like mdd and others who defend the “old’ shittah.
I have all the respect for Rav Shteineman shelita (contrary to what you may think, harotze…) but ,for the life of me, I don’t know where this “new’ shitta comes from. Until the second world war, kollels were rare- for the best of the best only-and most people worked,even in the heart of Lithuania!. As it was for three thousand years. What happened in the past fifty years to changed this?? Did maaseh bereishis suddenly change?? On another post some time ago, I divulged that I have two sons in kollel, but they are not there forever (one has already taken a post) and if they would not be suitable for some kind of ‘klai kodesh’,of course, they would go to work , like other people.
By asserting (as mdd said) that EVERYONE has to be in kollel forever, you actually diminish the importance of kollel and you are not able to feed those who really should be there adequately.
Lastly, it may very well be that Rav Shteineman shelita is being misquoted by the original poster (OP) and all he said that we must learn more Torah and may not have said anything about not engaging in work.
