I think it's mostly just lack of caring, not arrogance, at least in my experience. Sure, some people react badly when you try to coax them out of their comfort zone. Could be a cultural thing - Americans seem to be more confident overall, which could well manifest itself as arrogance in this situation.

I come across the issue occasionally as a contractor - where my work needs to be integrated with the help of employees who are totally out of their depth with it. In addition to making it all happen you get a second objective: not embarrassing them or otherwise pissing them off.
