At the end of the day people value Educators, Healthcare workers and such less than other jobs.

The highest paid jobs are those where value can reach millions of people. Such as Iphone: Millions of people buy iphones and only a limited number of workers benefit from such sales. If each healthcare worker could serve millions of people they would have higher pay per year. Unfortunately they are limited in how many people they can serve per day. Maybe technology will change this and allow for higher pay for less healthcare workers who are able to serve more people each day.
