There's an argument to be made that at least the bachelor's level should be taught by specialist lecturers who focus on improving didactics and teaching. On the other hand, interacting with someone who is working at the forefront of the field can be helpful when you have a question where a cookie-cutter answer doesn't suffice and expert thought is needed. But it's indeed peculiar that profs are mostly hired based on their research not on their teaching ability (though it is also considered).

But either way, since you mention the US, it's a very common experience for American exchange students in European universities that in America they learned to expect much more handholding and pampering than it's provided in Europe. In the US, there is more individual attention from faculty to students, there are all kinds of counseling and guidance services that basically nudge them through the whole thing, reminding them of deadlines, explaining processes etc. In the US, college students ("college kids") are not seen as self-reliant adults. So depending on what kind of "support" you mean, it might be already too much for their own good instead of little.
