What were some long- term effects of the court's decision in the slaughterhouse cases?

The Slaughterhouse Cases (1873) significantly limited the scope of the Fourteenth Amendment's Privileges or Immunities Clause, establishing that it primarily protected national citizenship rights rather than state citizenship rights. This decision effectively curtailed the federal government's ability to intervene in state regulations, allowing states to impose laws that could infringe upon individual rights without federal oversight. As a result, the ruling set a precedent that hindered civil rights advancements and contributed to the systemic inequalities that persisted in the post-Reconstruction era, particularly for African Americans. Overall, it reinforced states' rights at the expense of individual protections under federal law.
