Utilitarianism — whatever most people say will make them happy is good — represents a type of efficiency. Instead of maintaining power structures, focus on what is immediately rewarded and later, in theory, attempt to improve that.
Nature inherently rejects utilitarianism by imposing hard limits. What you and your buddies “think” will make you happy has no bearing on what you need, such as food, water, shelter, and enough stability to successfully reproduce for multiple generations.
If you leave it up to efficiency, you get a highly generalized product. Easy Cheese tastes minimally like cheese, and most emphasizes convenience and the generic things that make food “taste good” to a plurality of people surveyed.
When you ask an audience what they like in food, they will respond with random gibberings, but they will consistently buy things high in vegetable fats, salt, sugars, and carbohydrates.
Whether by free market or communism, when we rely on the Crowd, we end up in the same place: a cheap substitute of once-great things, sold at a high price because it comes in a spray can.
