(Black) Markets in Everything

Students at a high school in Austin, Texas gave their teachers a lesson in the economics of prohibition.

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."

Thanks to Sean Brown, a student at another Austin high school, for the pointer.
