We can also say this is a failure of culture too. Let's take a look at doctors: why do they need so much education in the form we do it now? You, dear reader, could almost certainly do a doctor's job after a couple years of apprenticeship, even if you aren't very bright.
Not that I'm anti education, i think everyone should have a broad education that is at the very least more comprehensive then what we currently have in America.
I kind of get the point you're trying to make but I very much disagree. This line of thinking is one of the reasons US healthcare is so hellbent on pushing PAs and NPs to fill the doctor gap. And it's not working because there is no substitute for a well trained doctor or specialist.
