Fast food is a subject that's near and dear to Clark's heart. The fast food chains are discounting their menus because they're hurting for customers right now. Wendy's has come out with the Stack Attack double cheeseburger for 99 cents, while McDonald's and Burger King have their own $1 double cheeseburgers. The fast food index is a leading indicator of difficulty in the economy. So you'll see value menus start to grow as disposable income continues to shrink. Fast food restaurants need their so-called "heavy eaters" -- people who are super-loyal to a particular brand and dine out about 5 or more times a week. Many heavy eaters are younger men who are price sensitive. As a bit of trivia, do you know who started the value pricing trend in fast food? If you thought McDonald's, you're incorrect. They've marketed it so well that you would immediately think of them. But Taco Bell actually started it on a national basis with their 59 cent value menu.
