Avira, I counted on your help :)!
Gadol, RebE, lofty concepts, but the reality is that majority of the people expect to live (at least) like others around them. If they don’t get a legit profession, they’ll get it another way. This is mefurash Kidushin 30. The modern machloket is whether we can be meikel and allow collecting money from non-Jewish social programs. But if you not a tzadik he can live poorly (married to a tzadekes) and you are machmir and insist on earning your own living – then your choice is between college and manual jobs. Many talmidei chachamim are not good at plumbing and hairdressing and would prefer accounting and computer programming. So, then, the question is – is it possible to acquire a profession without spiritual risk (Gadol’s approach to disregard the risk entirely sounds like an ostrich policy that failed in previous generations).
