That hasn't been my experience when working with or attempting to hire bootcamp grads, but I'm glad that it happens in some cases! I've seen a lot of HS-to-professional types, some with some college and some without.
I've been in one bootcamp class so my results may not be representative :-).
However I also get the feeling that being a developer has become more visible as well paying, in demand job similar to being lawyer was a decade or so ago. A lot of people wanted to be lawyers not because they were passionate about law but because they knew they could make a lot of money.
I get the impression that many people are drawn to boot camps by ads along the lines of "Make $XXk+ being a dev in X weeks" as opposed to being interested in the field.
Every single person in my boot camp class had a college education. One person was a college professor prior to attending. Several people actually had CS degrees that they felt didn't prepare them to do actual practical programming. We also had a lawyer and a couple of people with mathematics and physics degrees as well.
