Exercise 4

In 1938 Congress created a Board of Cosmetology in Washington, D.C, to license beauticians. To obtain a license, people had to attend a cosmetology school. In 1992 this law was used by the board to close down a hair braiding salon specializing in cornrows and braids operated by unlicensed Mr. Uqdah, even though little was then taught in cosmetology schools about braiding and cornrows.
a.What possible reason can you give for why this board exists?
b.What options might you propose to change the system?
c.What will be the political difficulties of implementing those options?
