Well, just look at all the teleshopping ads. They do all the dramatization, with complex stories and inventing problems you don't actually have, and then comes the amazing product that efficiently solves this horrendous problem. They are not lying about what the product does, but they are lying about how it will actually affect your life. This also happens to most of the "self-improvement" books that promise you that you will get rich in 7 days, out of which the last 3 you can just spend to get a 6-pack. The idea is that a product "could" affect your life in a specific way, but it most likely won't in the way it's advertised.
