I hope you see that my point isn't that nursing is easy, my point is that (in the US) the pay is very high and the barrier to entry is moderate. So it becomes a magnet for people who just want to make money. This becomes even more true for med tech jobs, where you can blast through a cert in a year, and land a $30/hr job pretty quickly. That's about 50% more money than people typically in that education class earn.
