Suppose you're a trucker with an interstate license to ship goods but you want to expand to shipping goods within your state. Is it fair for the government to permit your competition to show up at your hearing, with their attorneys, to protest that your services are not needed and therefore you are denied what's called a "certificate of necessity," which would allow you to ship goods within the state? Attorney Timothy Sandefur discusses this despicable process in his recent article "CON Job," published by the Cato Institute (summer 2011). "Certificate of necessity" monopolistic restrictions exist across the country, governing a variety of industries, from moving companies and taxicabs to hospitals and car lots. The intention and the effect of these laws is to protect incumbent practitioners from open market competition, enabling them to charge higher prices as a means to higher income.
Interior designing has almost no startup costs. Not so if you want to practice in Florida. State law mandates that anyone who wants to practice interior designing have six years of education and experience, including graduating from a state-approved interior design program and completing an apprenticeship under a state-licensed interior designer. Then the applicant must pass a state-mandated licensing exam. The sole purpose of the law is to keep the outs out so the ins can charge monopoly prices.
If interior designing is not for you, how about being a tour guide in Philadelphia or Washington, D.C.? Neither city will permit you to be a tour guide without a government-issued license.
