Or Philosophy is usually a path to Law School on the professional path or a PhD on the research/academia path. In both cases, many/most of those 22-27 year olds are still in school and thus not counted as unemployed.
I don't know how true it still is with law being, to a fair degree, perhaps primarily a good career path for those who can land at white-shoe firms and federal court clerkships. But I've known a lot of people who drifted into law school from liberal arts and related because they just didn't have great job prospects. And quite a few didn't even end up practicing law.
