This essay critically examines the efficacy of race-based affirmative action in U.S. college admissions, arguing that it fails to adequately address the root causes of racial inequality and often does not benefit the most marginalized individuals within minority groups. By exploring affirmative action through the lens of political philosophy, particularly John Rawls' conception of social justice, the essay contends that a focus on socioeconomic status rather than race would more effectively promote equality of opportunity and align with Rawlsian principles. The analysis draws on various studies and theoretical perspectives to highlight the limitations of race-based affirmative action, including its tendency to benefit economically advantaged members of minority groups and its inadequacy in addressing the diverse and complex backgrounds of individuals within these groups. The essay proposes socioeconomic affirmative action as a more equitable alternative, supported by empirical evidence suggesting that such an approach could increase both socioeconomic and racial diversity in higher education institutions. The conclusion underscores the need for systemic reforms beyond admissions policies to truly achieve a just and equitable society.
