If someone is skilled at IT, deeply understands computers and networking, and has critical thinking skills, they can get a better job. There are few people like that anywhere. Why would they be sitting around in IT? They should be designing a router.
And frankly speaking, they don't need to know the deep depths of how everything works. It would be silly for a hospital to demand that every staff member have the highest level of education. It's a waste of resources. The vast majority of work can be done by less skilled people. Just like in a hospital, if a diagnosis seems difficult, you can bring in the expert. You don't need a building full of experts. Sure, it would be nice, but the waste would be staggering.
