Everyone likes the idea of equal opportunity. This economist thinks it’s a fantasy.:
Another remarkable feature of the surname data is how seemingly 
impervious social mobility rates are to government interventions. In all
 societies, what seems to matter is just who your parents are. At the 
extreme, we see in modern Sweden an extensive system of public education
 and social support. Yet underlying mobility rates are no higher in 
modern Sweden than in pre-industrial Sweden or medieval England.
There was one case where government interventions did seem to promote
 mobility, which was in Bengal, in India. There the strict quota system 
in educational institutions had benefited significantly people with 
surnames associated with the Scheduled Castes.
