Most states require barbers to receive instruction in bacteriology and diseases of the skin, hair, glands, nails, and nerves. Georgia has an unusual requirement for those who seek to become a licensed commercial photographer-they must pass a Wasserman test for syphilis. I don't know about you, but a photographer has never been quite that close to me that whether he has syphilis would be a concern. Licensing laws stifle entrepreneurship in many ways. The most immediate effect of licensing is a restriction on the number of practitioners, because of the higher entry costs to meet the qualifications of the licensed activity.
Some licenses require many months of schooling, as for cosmeticians and barbers.
Other licensing laws require the installation of costly health and safety equipment. Yet others require the purchase of a license or a certificate of authority from an incumbent practitioner that can cost into the millions of dollars, as was the case when interstate trucking was highly regulated in our country. Some licensing jurisdictions issue only a fixed number of licenses or authorizations. All of these requirements raise the cost of entry which in turn leads to a restricted number of practitioners. A secondary effect is that the price of the good or service is higher than it otherwise would be.
