How are nurses and paramedics "equal"?
Lots of hospitals employ Medics to work in the ER, right along side nurses. Literally, the only difference is that nurses can insert foley catheters and medics can't. Many times, the medics know more about medications and procedures than the nurses do.
So I agree there is an equality issue. In fact, I'll take it to the next step... to be a medic and work in the ER, all you have to do is apply for and get the job -- you've got all the requirements you need. However, a nurse (even doctors) must be certified and licensed as an EMT to work in the field.
