You could rephrase your sentence and replace "higher social class" with race, gender, religion, or member of my favorite club and you'd have the most base -ism

You could rephrase your sentence and replace "higher social class" with race, gender, religion, or member of my favorite club and you'd have the most base -ism ever. This sentence is the root of almost all discrimination. "Therefore, if you do not know anything else about a group of candidates" Then the solution is to know more. Often our stereotypes (higher class) mask deep incompetencies or stop us from a deeper evaluation of the talent. You substitute accent, mannerisms and fashion for evaluating skills, aptitude, experience for the false assumption that in general will rule over the specifics of the candidate pool... which leads to horrible hiring practices, dystopian culture and worse.
