This is from Kiddushin, page lamed (30) side beis (2).
The father is obligated to teach his son a craft. From where do we know this? Chizkiya said: "For the verse states: See life with the woman whom you love." Life connotes craft (for a livelihood) and is here next to woman. If "woman" is to be understood literally, then just as the father is obligated to find his son a wife, he is obligated to teach him a craft. If, on the other hand, "woman" is to be understood allegorically to mean Torah, then just as the father is obligated to teach his son Torah, he's obligated to teach him a craft.
Rabbi Yehuda says that anyone who does not teach his son a craft, teaches him banditry.
Gemara asks if this is what he really meant and answers that what he meant was that it's as if he teaches him banditry. Since his son doesn't know how to do anything, his only means for supporting himself is by stealing.
Gemara places Torah, wife and a job on the same level and obligates the father in all three equally. No one comes to defend the father and say that he should get his son a rich father in law or that the son should steal money from the government or go collecting charity or sitting and praying onto G-d to fedex him money every month. Just as you're supposed to teach your son Torah and to get him a wife, you're supposed to teach how to go out and earn an honest living. The response of today's yeshiva rabbis is a two prong attack on this "fallacy". One, condemn secular education, the one needed for getting a job, as evil and not part of Torah leaving. Two, condemn working people as criminals who are wasting their time working instead of learning Torah.
My cousin works as prison guard in Colorado. I was talking to him on the phone and he asked me "Did you know how many Jew are in prison?!", "Yeah, wanna know why?"
