Here’s just a quick little something to think about.
At McDonald’s, you can buy a hamburger for 89¢, a cheeseburger for 99¢, and a double cheeseburger for $1.
Using some serious math that I’m not going to explain because you won’t understand it, this works out to 10¢ for a slice of cheese, 88¢ for a bun + ketchup + 2 soggy pickle slices and some minced onion, and 1¢ for a beef patty.
This should make you wonder about some things.
EDIT (3/13/06): Never mind. This educational game pretty well explained everything to me that I wanted to know.
