Easy to favor simplicity when the basics in your field hasn't been fully mapped out yet. Much harder to make a name for yourself when pretty much all the low-hanging (i.e. simple) fruit has been claimed already by people in the past. Most people probably feel they don't have much choice but to pursue more complex ideas nowadays as a result.
I've shown these ideas to many so-called well-educated college graduates, and they don't warm up to it. They say "processes" > "individual initiative". This is too old-school, too simple, blah, blah.
I think people will learn only when you put them in charge of a complex undertaking to appreciate what simplicity means in leadership of complex projects.
Partly this, and partly because average college professors are being compared to some of the greatest scholars of all time.
Figures like Einstein or Feynman were able to simply inherently difficult/complex problems well into the 20th century, and similar people are surely doing the same today.
But often a difficult problem needs to be understood the hard way before it can be simplified down to something that is easier to communicate.
