While I cannot respond as a doctor, I can respond as an EMT. Totally different. But heres the deal.
The person who is the most important to you on the worst day of your life is the emt. The interview was literally "do you have a drivers license, and are you grossed out by stuff?" The rest you learned on the job.
Weird how doctors are vetted but prehospital folk are not.
edit yes there is training, but it happens after hire
The person who makes the ball bearing in the ambulance is also super important. They are paid leas because more people can do it.
The reason why EMT have such hiring practices are because many people can do the job, and there are many willing to do it.
It’s not weird if you think of in market terms.
