Unattractive people should be legally protected against discrimination, according to University of Texas at Austin professor Daniel Hamermesh.

Studies have found that employers are more likely to hire good-looking candidates and that less attractive people earn less than their more attractive peers.

"Logically, I see no difference between this and other protections," he told CNN on Tuesday. "Perhaps not with racism. Politically, I'm much more concerned about racism... but between this and physical disability, I see very little difference. We happen to protect one and not the other."

Although attractiveness may be more important for women than men in social life, studies have found attractiveness is more important for men in the workplace, according to Hamermesh.

"We already do this in a couple of locations in California, in the District of Columbia and France," he added. "Is it going to happen soon? No. Will it possibly happen eventually? I wouldn't bet against it."
