American colleges give way more support throughout the studies though. In Europe you're literally alone and nobody cares if you miss deadlines or you're failing out. No general consultations, no extra departments and admin bloat. You have to have your shit together.

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.
