^ Might I say that there are very incompetent people that are overemployed and very competent people that are underemployed. This does not reflect the job title or function of "medical assistant" but the labor market as a whole. There are some that miscalculate the height of a person. There are some that miscalculate the rewards of prolonged military commitments. The difference is that one went to vocational school, because that is what their resources allowed, so now they calculate incorrectly in inches while the other was a legacy admit at prestigious schools, because that is what their resources allowed, so miscalculated in Trillions of Dollars. Conversely, there are some that were doctors in their homeland, but now they are self-employed as convenience store owners. There are some that are middle aged that had no opportunity for higher education although they were very bright, so they are now construction workers. ETA: Sometimes it is a clinic's policy to adjust certain measurements to compensate for added height by shoes and added weight by clothes. However, an inch or pound or two or even three will not changes a person's BMI calculation much.
