Is a prestigious undergraduate degree worth it?

I’m in the legal profession (20+ years), and my thought is that undergraduate college prestige is a very small part of the law school admission process. For example, if a student from Harvard has a 3.8 GPA and another student has a 3.8 from a state flagship university, I can see the Harvard student having a slight advantage, assuming similar LSAT scores. But I think it’s minimal and that slight potential advantage would not be the reason to spend extra money to go to the Ivy League college. Besides, there are less than 10 law schools that have truly portable degrees, and the chance of getting into one of those schools is really low. So most students will end up at a regional or local law school, at which point admission is not as competitive although competing for scholarships would be.
