A majority of the people in the AA programs have had some healthcare experience. Whether it's volunteering or an actual job, I think both can be valuable learning experiences. During the program, the student is exposed to over 2500 clinical hours. Why is someone that is starting their first job after graduation expected to be an expert in dealing with patients? It's going to take time and it will come with practice. Some will catch on faster than others.
I also take offense to the basket weaving degree comment. Although there is no specific degrees required to get into the program, most have received biology or chemistry degrees. Plus, it's a requirement to have all the science/math prerequisites. This is similar to any medical school, which doesn't specify any particular degree and requires no healthcare experience.
