Market Economics 101

When Austin High School administrators removed candy from campus vending machines last year, the move was hailed as a step toward fighting obesity. What happened next shows how hard it can be for schools to control what students eat on campus.

The candy removal plan, according to students at Austin High, was thwarted by classmates who created an underground candy market, turning the hallways of the high school into Willy-Wonka-meets-Casablanca....

"It's all about supply and demand," said Austin junior Scott Roudebush. "We've got some entrepreneurs around here."

This from the comments thread is great...

Rick: Last night we said a great many things. You said I was to do the thinking for both of us. Well, I've done a lot of it since then, and it all adds up to one thing: you're getting on that schoolbus with Victor where you belong.

Ilsa: But, Richard, no, I... I...

Rick: Now, you've got to listen to me! You have any idea what you'd have to look forward to if you stayed here? Nine chances out of ten, we'd both wind up in detention hall. Isn't that true, Louie?

Captain Renault: I'm afraid Principal Strasser would insist.

Ilsa: You're saying this only to make me go.

Rick: I'm saying it because it's true. Inside of us, we both know you belong with Victor. You're part of his work, the thing that keeps him going. If that schoolbus leaves the parking lot and you're not with him, you'll regret it. Maybe not today. Maybe not tomorrow, but soon and for the rest of your life.

Ilsa: But what about us?

Rick: We'll always have French class.

(Incidentally, the first comment by M. Simon is serious, however.
Also worth a look.)
