Which is why it might as well be the pro-Gillette marketing zeitgeist. Too easy to turn away from something under the assumption you'll just get sucked into it and waste a lot of money. Another good example of this is the fountain pen community. As a total outsider, I was actually under the impression that a fountain pen cost well over $100 and was difficult to maintain and write with. I happened to randomly look into it one day only to discover that some very well regarded pens are only $30 or so, write well on almost everything, and will last for years of high quality writing.
If some people want to turn it into a hobby where they obsess over badger hair brushes and so on, that's also fine. Nobody is ever forced to buy that sort of stuff.
All marketing tries to mislead people to spend money on "unnecessary" stuff. That's what people mostly spend their disposable income on. And Americans have tons and tons of disposable income, so they are good targets for marketing. I don't see the same thing in Germany for example as people are generally more careful with their money and don't have ginormous amounts of it like Americans (look up the disposable incomes). For example, you're (assuming you're American) also getting screwed by the mattress industry.
