This is a video by Thomas Sowell, an American economist, political commentator, and senior fellow at Stanford University’s Hoover Institution. It is mentioned in the video that academics, except those subject to testing such as science and mathematics, is not serving society well which I agree with. But unfortunately, Thomas talks only about the left wing while the right wing is not only serving society but also hurting progress. This shortcoming of Thomas is I believe due to his rightwing inclination.
