Yep. History professors read about the Battle of Berlin. They write about the Battle of Berlin. This janitor was actually at the Battle of Berlin, holed up in a building with a panzerfaust (a German anti-tank weapon). He was a living witness.
Yet all those professors walked right past him as he mopped the floor.
Social Science Professors with Ph.D.s are some of the most arrogant men and women on the earth, especially hard core leftists. To paraphrase Winston Churchill-they love working people. The love to watch them work as they walk by to the faculty lounge for a two hour coffee break.
