Naked economic protectionism is alive and well in interior design, according to Clark Neily.

Imagine you were a state legislator and some folks asked you to pass a law making it a crime to give advice about paint colors and throw pillows without a license. And imagine they told you that the only people qualified to place large pieces of furniture in a room are those who have gotten a college degree in interior design, completed a two-year apprenticeship, and passed a national licensing exam. And by the way, it is criminally misleading for people who practice interior design to use that term without government permission.

You might stare at them incredulously for a moment, then look down at your calendar and say, "Oh, I get it -- April Fool!" Right? Wrong.

These folks represent the American Society of Interior Designers (ASID), an industry group whose members have waged a 30-year, multimillion-dollar lobbying campaign to legislate their competitors out of business. And those absurd restrictions on advice about paint selection, throw pillows and furniture placement represent the actual fruits of lobbying in places like Alabama, Nevada and Illinois, where ASID and its local affiliates have peddled their snake-oil mantra that "Every decision an interior designer makes affects life safety and quality of life."
