If you bought an expensive engagement ring, then the answer is yes.
Economists develop models of how the world works based on the assumption that consumers are rational utility maximizers. Anybody that has seen a television commercial knows that the marketing industry operates on the assumption that this is not true. SUV's climbing near vertical walls, celebrities telling you that certain credit cards are great. Those celebrities will say the same about the leading competitor's product if that competitor had paid more. The appeal is completely irrational.
But at least a car is useful. What about the diamond engagement ring? I don't think so. The symbolism was concocted out of thin air as a means of enhancing profits for DeBeers Consolidated Mines, Ltd. And what's tough is that it's a financial burden placed on a person at a time in his life when it is generally harder for him to manage it. That's one of the issues discussed in this article: 7 Reasons Why Diamonds are a Waste of Your Money.
In fairness to economists, the "rational utility maximizer" is an understandable assumption. Assumptions are required in order to develop models that predict behavior. It's true that people generally don't buy things because they want to harm themselves. But our irrational consumptive tendencies must be kept in mind, because on unregulated free market capitalism we should expect companies with huge concentrations of wealth to seek to exploit those tendencies to improve their own profits. Even when the consumer is harmed.
