As a college non-graduate, I think that is leveraging the strong data that for most people a college degree is a huge net benefit is reasonable.

As someone who was once <25, I think that version of me is stupid in a wide variety of ways. I hear you that it can be negative to divide things that way, but it seems reasonable to say “after you are either a non college graduate with a number of years of experience or a college graduate with ~2 years of post-college experience.

I hear you, though, it’s hard to sort people into buckets.
