http://www.washingtonpost.com/wp-dyn/content/article/2006/12/09/AR2006120900925.htmlInnovator who didn't want to price-gouge his customers was recently crushed by legislation as a result of a heavy lobby.
No where in this story is he getting crushed by fierce competition (like how Walmart crushes mom and pop stores), but instead is crushed entirely by lobbyists for the Milk Industry.
As boring of a story as this sounds, it's a fascinating representation of the damages of "government regular."
