"The New Jim Crow" by Michelle Alexander is a profound exploration into the racial dynamics of the American criminal justice system. The book posits that despite the outward appearance of a post-racial society, particularly after the election of Barack Obama, a new form of racial caste system has taken shape. Alexander meticulously lays out how the War on Drugs has disproportionately targeted African American communities, leading to mass incarceration and the systematic disenfranchisement of millions of African Americans. Her work challenges readers to reconsider their understanding of race relations in the United States and calls for transformative changes in policy and public consciousness. More than a book, it has sparked widespread debate, fueled social movements such as Black Lives Matter, and continues to shape discourse on civil rights in the 21st century.
