I fully agree with Jed that it is not a local thing. In fact, it is not even exclusive to the photography industry at all.
I'm not sure what experiences you've been through, and they are obviously pretty bad ones. The reason why I am extremely selective about my apprentices is exactly because I want to devote the time and attention to impart my skills and knowledge to each of them. And the reason for my philosophy is because I was a beneficiary of such tutelage. And no, I didn't need them to hold my hands through the nitty-gritties. I don't hold the hands of my apprentices either, but I always encourage them to question, and even train them on their questioning. I see CS as an extremely generous sharing ground, contrary to what you seem to imply. Unless you were really talking about step-by-step-tell-me-what-to-do-next kind of tutelage.
