You see similar things in academia too. Used to be that a Professor was truly a high honor and skill set to be admired and desired. Now all of the "professors" you're likely to come across are just guys and gals doing a bunch of their own research who and being more or less forced to teach to earn their keep......and it shows. No wonder students loose interest. Their teachers don't even want to be there. Meanwhile, great teachers who can/do have the drive and enthusiasm it takes are left on the sideline. Good grief
This isn't new, actually - it was the case when I was doing my post grad work in the late 70s.
