Op-Ed from a Milwaukee newspaper making the case that Wisconsin occupational licensure requirements are stifling entrepreneurship in the state. The article makes the point that these regulatory hurdles are often implemented because those within the profession already seek to insulate themselves from outside competition.

The article goes on to list different professions (interior designers, art therapists, music therapists, dietitians, landscape architects, massage therapists, behavior analysts and barbers) that all currently require licensure in Wisconsin. The author emphasizes his support of Gov. Scott Walker’s recently introduced proposal to review licensure requirements for these professions with the hopes of spurning entrepreneurial activity.

I dug around for a few more articles and a lot of what I found supported the idea that licensure requirements, particularly for low to moderate income entrepreneurs in occupational fields faced significant barriers to entry by way of fees, and course and exam requirements.
