Fortune Small Business: “If you want to become a florist in Louisiana, a state law requires you to take a licensing exam. Your flowers are evaluated by licensed florists on subjective criteria such as whether they are ‘spaced effectively’ and have the ‘proper focal point.’ More than half of the applicants fail. Do unlicensed florists present a big menace? No, many believe the real explanation is that Louisiana florists want to limit their competition. In Oklahoma a similar law requires that anyone who wants to sell caskets must first obtain a funeral director’s license and embalm 25 bodies. These laws and others like them can seem unfair to entrepreneurs, and in recent years a nonprofit law firm called the Institute for Justice has helped small businesses fight them.”
