> If I buy literally any kind of consumer product, it has planned obsolescence built into it. Some do, but plenty don't. And plenty have "this part is rated for X hours of use" where X is all designed around some common expected lifespan. > If I go to a wealth manager, they will try to sell me the investment/pension fund that gives them the best commission. This is true of some managers. It's also why some advertise that they are fee only (that is, they only make money off a fee you pay them with no commission) and why there are laws if they advertise themselves as fiduciaries (they are not allowed to consider their commissions). > If I go to a dentist he will try to sell me on treatments that will earn him the most money. I mean, all medical (and legal among others) professions suffer from the fact that the person selling you something knows better than you do what services you need. This is a real problem, and is often dealt with by professional codes of conduct and oversight boards. At least dentists seems so in demand that they don't need to invent work, since most people don't verify a cavity exists.
