Marginal practitioners and limited practitioners (see question below)

The textbook makes a distinction between marginal practitioners and limited practitioners in the field of chiropractics. Within these two categories, one is considered to have a low social status and the other a high social status. Should such distinctions be applied to the profession? Please defend your position with supporting facts and references.

Your response should be at least 300 words in length. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations. Any references or citations used should be in APA style. Please include at least two peer-reviewed articles as references.
