I've often wondered the same thing. Not only what they want, but how they can possibly afford it. Often those same people seem to be rather clear that money is tight and they can't afford things that seem like they ought to be rather more important.

As for your list, I would add things like plastic toys (well, not so much plastic, as premade things that are almost knickknacks), ridiculous "gadgets" that are more gimmick than use, restaurant meals, and packaged foods.

Then again, I (and my family) tend to be the practical sort who like making things, which might bias my list a little.
