Yes, even reputedly good schools are garbage, and I went to one of those as well.
The key thing for me is: What do they teach you? Anything you can use in your life? No, literally nothing at all - at the end, you're worse off in real life than if you hadn't gone.
They don't teach practical skills, money or investing, how to network or even get a job - just utterly useless and actively harmful.
