WORKING-class people have to work more to “achieve that which is gifted to others,” a Labour MP warned today, after new research reported a £6,700 “class pay-gap” in Britain.

The Social Mobility Foundation said professionals from working-class backgrounds are being paid an average of £6,718 less than peers from middle-class backgrounds, effectively working for free nearly one day in every seven.

According to the group’s study, the pay disparity increased when the working-class professionals were women or ethnic minorities, giving them a “double disadvantage.”
