I definitely agree with what you're saying, especially in startups it really isn't that relevant (part of why I like the startup community so much). But I do spend a lot of time outside startups as well, and that glass ceiling is definitely present in large companies and academia (especially academia).
I wasn't clear. Having a degree is important and not having one is often a blocker. For example, you can't get a mechanical engineering job without a degree. (There are legal reasons for that as well.) Where it is from does not matter, nor does your GPA.
