I don't understand america

Why is it that everyone across america has this compelling desire to buy the newest things at the opening sale for a ridiculous price, like the PS3 and the Wii. why can't they wait a few years and buy it at a reasonable price? Hd is alsmost within reach, but it will probably be better priced in the early/middle of next year. I've seen on tv, people waiting in line at 3 in the morning before the stores open and runnin g about like mad things throwing everything on the shelves into their carts and maxing out credit cards. I see them as complete idiots wasting a lot of money.
