The actual cost of TVs did not fall by 90%. Back in 2000 most of us were buying tube TVs for $400 while the brand new HDTVs were $3000. And how about TV service?

EDIT: the four different ways to spend money by Milton Friedman

1) You can spend your own money on yourself.

If you spend your own money on yourself, you're very careful on what you spend it on. You make sure you get the most for your dollar.

2) You can spend your own money on someone else.

When you spend your own money on someone else, you're careful on not spending too much. You don't worry as much about the gifts you buy for other people as the things you buy for yourself.

3) You can spend somebody else's money on yourself.

You're careful to get good things for the money. But you're not very worried about getting the best bang for your buck. You're happier to spend more of somebody else's money within reason.

4) You can spend somebody else's money on somebody else.

You become a “distributor of welfare funds.” You're interested in making your own life as good as you can. But you're not going to be anywhere near as careful as spending this money on other people.
