In economics only. Rand and Marx both were firm believers that only a few people are capable of leading all the other riffraff. (Rand believed that depravity was inherent in human beings). This is the concept of the 'proletariat', the epitome of communist philosophy.

Also, they both viewed people as bundles of various psychological attributes, and not as human beings with spirits and souls.
