When you used the word 'mindless' in describing what I have called 'arbitrary discrimination' (and appropriately so) it made me think about motivation. Most businessmen are motivated by production, profits and quality service. The businessman who is mindful of that will discriminate in hiring on substantive issues like education, experience and talent. The businessman who allows personal prejudices to affect his decisions will not be competitive. Thus racism, sexism and the like become self-limiting practices.
That kind of philosophy is progressive in practice not in name unlike the regressiveness of Progessive (communist) philosophy which promotes reverse racism as a remedy.
Well stated and I concur wholeheartedly.
