I work as an executive in healthcare administration, and I have to admit that depending on the college/university, an undergrad degree in biomedical science may not equip you to do much of anything. It is a degree primarily designed for people looking to be admitted to medical, dental or pharmacy school, or who plan to go on for a research-based graduate degree in some aspect of human biology or medicine.
Some of these programs do offer certain areas of emphasis, such as lab technology, cell biology and the like. Does your friend have experience working in a clinical lab? If so, a hospital or clinic lab may be a possibility. Pharmacy techs are always in demand, but since there are so many of them, it is not the best-paying job, as your friend has found out. If your friend works in an area of biotechnology companies, perhaps that is an option. They are always looking for bottle washers, animal care and bench technicians.
Generally speaking, if your friend is looking for a healthcare job paying $ 20 per hour, these are usually found in more technical fields by people with degrees in those fields. An example would be a radiology technician, who has a two year degree from a community college, and can probably start at $ 45 K or so, depending on the location.
Please let us know if your friend has any specialized training or skills, and perhaps we can be of more help.
