Why do people recommend PA to medical students and premeds?

Why do people recommend physicians assistant to premeds who don't get into medical school or to medical students who fail out of medical school? Isn't PA school just as hard to get accepted into, and it's PA just as difficult as medical school? I figured physician assistant schools are just filled with medical school quality students who didn't want to invest 7+ years of their lives and crazy student loans to train for a job. Am I wrong here?
