In the UK, a 2015 government study by the Social Mobility Commission suggested the existence of a "glass floor" in British society preventing those who are less able, but who come from wealthier backgrounds, from slipping down the social ladder. The report proposed a 35% greater likelihood of less able, better-off children becoming high earners than bright poor children.

The association of particular ethnic groups with class statuses is common in many societies, and is linked with race as well.

The labels ascribed to an individual change the way others perceive them, with multiple labels associated with stigma combining to worsen the social consequences of being labelled. As a result of conquest or internal ethnic differentiation, a ruling class is often ethnically homogenous and particular races or ethnic groups in some societies are legally or customarily restricted to occupying particular class positions.
