all they could do in life after their profound accomplishment was repeat what was told to them to children.
I'm not sure you're aware, but most professors are researchers first and foremost, and educators second. I would recommend familiarising yourself with academia before passing judgement on it. Avoiding elementary errors like that will make you look less silly, and you may even find it will increase the persuasive power of your arguments (albeit at the consequence of their content changing).
Professors take jobs at universities primarily to teach, not do research. The University forces them to do research for their own profit, and emphasizes that role as it can be very profitable for the institution, but that is besides the point. No one goes into professorship because of the research.
See
http://www.nea.org/home/33067.htmFull-time, tenured faculty must serve on academic committees and, at most four-year colleges and universities, conduct research as well. In spite of these requirements, faculty responding to surveys overwhelmingly report that teaching is their favorite responsibility and that they do more teaching than anything else. According to a government survey, even faculty at research universities spend considerably more time teaching than conducting research.
Professors don't want their careers to live or die depending on how well they do their research. They don't want to do the art of bringing new things into the world. They just want the easy job of repeating the same things over and over to endless classes of students. If they wanted to create new and wonderful things for the world they would have gone to work for a research lab or a tech startup, or they would have created one of their own.
They are afraid of failure, and would much prefer the comfort and security of an easy position of repeating themselves to children.
