It's ok that you don't believe a problem exists, but that doesn't make the people who do believe it exists into swindlers.

Someone selling solutions to a problem the salesman doesn't believe exists is a swindler. But yours are not the only possible beliefs, and having different beliefs than you doesn't make someone a swindler.
