Math says that's stupid. You can still do everything with a "meg" of RAM that you could do in 01987. In fact, the "meg" of RAM you get now is enormously faster, and you can interface it to other things that you couldn't get at the time, such as SSDs, so you can do strictly more with it.

Economics says you're spending newly abundant resources freely in order to conserve those that are still scarce. Economics also predicts that people will adapt to RAM prices doubling by using RAM more frugally, spending more of other resources to compensate.
