This guy is probably employing a Science methodology and is mistakenly blaming an entire discipline for achieving non-scientific (non-discriminatory) outcomes.
He's making the typical mistake you see all the time here.
Its not the discipline of Economics that is the problem its the Platonistic/Liberal Art methodology employed 99.9% of the time within that discipline that starts with the thesis first that leads to this type of insanity (ie "a disqualified mind" Rom 1:28) :
Got a big laugh in my class this afternoon. "In most sciences if reality and the model don't match, then the model is deemed wrong. In economics that's taken as evidence that there is something wrong with reality." Thing is, I wasn't trying to be funny.— Robert J Frey (@financequant) September 12, 2019
This methodology does not perform the basic discrimination function of the Science methodology and should be banned in education.
