It really depends on the university. Mine wasn't particularly helpful in this regard. They sent me a form-letter warning by mail once, when my GPA sank too low one quarter (this was before email was ubiquitous). And they did have some counseling resources available, but the resource-to-student ratio was very, very low. I would not call it white-glove service by any means.

Perhaps you also don't have a comprehensive picture as to what is available to students across every university in Europe. Europe, like America, is a big place and, like America, the situation probably varies by institution. As with most things, the answer is probably more nuanced than general observations would make it seem.
