I suspect it only looks like there are a lot of high paying jobs, because they are so much harder to fill, due to a there being so few qualified candidates... hence the high pay. Supply and demand.
Supply and demand is also influenced by ability to become qualified. I'm not qualified to flip burgers, but any fast food place could get me qualified in just a few hours. I'm not qualified to be a doctor and it would take me years of training to get that qualification. I've met people who failed to qualify as a burger flipper - you can correctly guess by that statement they are very disabled, I've met many who failed to qualify as a doctor, and all are smart people since people who are not wouldn't even try.
