I want to demonstrate how racist attitudes contribute to make the individuals cease to believe in themselves, resulting the social and professional failure.
Just to add to Ana Sofia's crucial hint, here's a classic socio-psychological study on the relationship between racism and stereotype-threat:
Steele, C. M. & Aronson, J. (1995). Stereotype threat and the intellectual test performance of African Americans. Journal of Personality and Social Psychology, 69, 797–811.
Moreover, you should look at the concept of "self-fulfilling prophecy" and its link to racism.
A book that covers these topics quite adequately:
Heatherton, T. F., Kleck, R. E., Hebl, M. R. & Hull, J. G. (Eds.). (2000). The social psychology of stigma. New York: Guilford Press.
I would encourage books that question the claim that whites, and only whites, are racist; and would recommend books that show that the reason we think whites are the only racist group is that white-created cultures are controlled by an establishment dedicated to diversity, mass immigration, and racial mixing, which has entailed celebration and advocacy of non-white group rights, as racial or ethnic groups, at the same time that whites are prohibited from doing the same. It is a double standard in which non-whites are allowed to show pride and express their ethnic interests, while whites are expected to celebrate diversity of other ethnic groups.
I am a little late at answering this question but recommend reading Eduardo Bonilla-Silva's (2003) book 'Racism without racists: colourblind racism'. One concept he maintains is Abstract Liberalism: that is, racist attitudes towards minority ethnic groups are projected in abstract ways in line with liberalism (I.e. 'We don't that immigrant in our country, not n evades of who s/he is but rather what they do not bring (economically). Same concept can apply in a professional context - 'we didn't offer him/her the job because of who they are but because they didn't have the skills/experience. Thus, majorised social groups can arguably justify their dominant position based on wider structural/ideological systems in place and not their own attitudes and beliefs.
