How to monetize ignorance? (specifically: about evolution)

The other day in my local public library, I came across a couple of books in the "Darwinism" shelf. Except these books were in support of "Intelligent Design."

The logical fallacies in those books were incredible to me. And they were plainly in print, and the authors were not embarrassed to be associated with them.

But then, about 75% of people (of all religions) in the U.S. do not believe in the theory of Evolution (even the more rational ones who do believe that the Earth is more than 6,000 years old don't believe in the theory of Evolution).

(As an aside: My mid-western U.S. town's public library has a large "religious fiction" section. I once conducted a poll in my university class to see who believed in the concept of Evolution, and only one student out of 13 raised her/his hand.)

So, here's my question. As a "go with the flow" kinda person, I don't want to fight the current. I want to exploit it. What are some creative^^ ways I can exploit this ignorance for cash money? I seek your thoughts on this.

^^One way would be to write books supporting "Intelligent Design", but too many authors already own that shtick
