When buying material goods, I think it we may be mistaken and shortsighted to only consider the purchase price and the satisfaction it will add to our own lives. What about negative externalities, like the future cost of having fewer resources to use for more important purposes, environmental degradation and rehabilitation, and the cost of dumping/recycling after use? These are all real costs of every purchase you make, but often not "included" in the price. Living on less leaves more scarce resources for use by others whether now or in the future, and sends less crap to landfills. Label me a moralizer if you like, but I think it is smart for society to encourage individuals to think beyond themselves. That capitalism has proven incredibly effective at driving innovation and efficiency does not mean we should defend its weaknesses as well as its strengths (better to work hard at mitigating them, to minimize the total overhead of the system).
