Each of these products is trying to convince you of their value, excess value really, so you will spend your money on them, yet the expense of the product isn't worth much. You need a house to protect you from the weather and other people. After having done that, the rest is extravagance. Jewelry is absolutely no value. If you can call, text, and browse the internet, you're good. If a car gets you from A to B and doesn't need a lot of maintenance, that's sufficient.
I remember a Sex in the City scene where Carrie was talking about her $40,000 worth of shoes.
Beyond providing the basics, these products aren't worth more except for their display of wealth.
Meanwhile, we destroy the planet a little more each day to prove we are worth mating.
