You might want to read up on Clotaire Rapaile, who is the de facto father of the modern SUV and record margins per vehicle for american auto brands.
One could argue quackery but this is C-level paying millions in consultancy fees quackery.
"Rapaille no longer sees patients. He doesn't need to, because he's paid well to supply his insights to corporate America - and lives in baronial splendor outside of New York City.
Apart from Ford, GM and Chrysler, he's advised companies like Kelloggs, Kraft, and Proctor & Gamble. They pay him to get inside the deepest recesses of our brains. In fact, he's known as the "car shrink" in Detroit." [0]
"The notion of need is very, very interesting. Because what do we really need, you see? I need food, I need water. I need shelter," says Rapaille. "And you know that, but then there are other needs, needs of identity. Needs of communication. Needs of being loved, being respected."[0]
"Why do you buy a car that doesn't even make 10 miles per gallon, doesn't fit into your garage? Do you really need that? And you don't need that intellectually," he says. "But at [...] the deepest part of you, the gut level if you want, you feel like you need that."[0]
"I don't believe what people say. They have a good alibi. They have a way to explain things to make them feel comfortable about what they're to do anyways," says Rapaille, who believes it's now considered hip to appear ready to take on anything.[0]
