With the caveat that this certainly doesn't apply to everyone: I think that a lot of millenials, especially those who went to selective colleges, have a hard time dealing with active supervision and negative feedback. I think this is because relative to previous generations, millenials were raised in a more coddling environment -- participation trophies, grade inflation, etc. I think that this coddling is especially pronounced with regard to high-achieving children/teenagers, who by the time they are in their early 20's have a track record of "success" (i.e., straight A's, high SATs, got into college of choice, got job of choice), and who have basically been set up to suffer major emotional trauma at their first encounter with anything that significantly diverges from "success" as they have come to understand it. On the non-millenial side, I think that people of a slightly older generation see themselves in a bit of a conundrum, in that they want to get top talent (technical or not) from the top schools, they perceive that "kids these days" are a bit more sensitive and less overtly competitive than they were when they were that age, and get a little bit scared about the possibility of fucking up and putting the hot new developer (who was a "big recruiting win") in tears. So, they treat the new kid with kid gloves and basically keep their fingers crossed that he/she will be able to do quality work just by figuring things out on his/her own. I actually don't think millenials themselves are responsible for any of the above. It's the fault of their parents, the general environment fostered by the elitist college-industrial complex that encourages everyone to aspire to a 4-year degree (and which idolizes those who go to the top schools), and subsequently managers who don't want to take the risk of actually helping the people under their charge develop professionally and personally.
