A Sociological Study That's Actually Needed

After reading about the latest nonsense from anti-vaccine parents, I wondered about the following questions:

1. What drugs are they on?
2. What drugs were they on in college?
3. What universities did they attend?
4. What did they major in?
5. What companies do they work for?
6. Did those companies need bail-outs?

The answers to the above questions might help us find out if there is higher-education bubble and, if there is one, where it's concentrated.

Addendum: They appear to be only high-school graduates. Maybe college is still worth something after all …
