There are places where you can have a good job with room for advancement as a single role medic. There are, however, many many many more places where this is not the case. I would also argue that everywhere I've worked the salary for nurses has been higher, sometimes hilariously higher. It's also much easier to go from RN-->medic than vise versa--Creighton University holds a 2 week course that would let an RN take their NREMT-P at completion. Nursing also offers significantly more career flexibility if you decide to leave direct patient care or find EMS too physically demanding. It is, for better or worse, an objectively better license to have from a career standpoint.
I'm not saying that people who become medics are wrong, or dumb, or anything like that, but I totally get why we tell new EMTs to get their RN over their medic.
