A large chunk of people think that every product should be certified as 100% effective and that just being able to read two numbers and see which one is the smaller number is the absolute maximum amount of work that should be required to be an informed customer of any product on the planet. Any defect in the product is "a scam," yet, anyone who pays anything more than the absolute minimum viable option is a total sucker. It's honestly a very strange way to view the world that I don't really understand. My source is that my mother is an ardent member of this group of peole. I find that it mostly just leads to the opportunity to complain about everything and build up a complex around you being "slighted" by the universe all the time.
