Rex and Tomlinson defined underclass as systematic disadvantage plus separate organization

Evidence

The concept of underclass was intended to suggest… that the minorities were systematically at a disadvantage compared with their white peers and that, instead of identifying with working class culture, community and politics, they formed their own organisations and became effectively a separate underprivileged class. (Rex and Tomlinson, 1979:275) From this point Rex and Tomlinson developed a model of political action and even a political agenda for black populations as they become a “class for themselves.” — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 2165
