Which issue did the constitution leave for later generations to solve?

The U.S. Constitution left the issue of slavery unresolved, allowing it to become a contentious topic that would ultimately lead to the Civil War. The framers opted for compromise, such as the Three-Fifths Compromise, which counted enslaved individuals as partial persons for representation purposes, but they failed to address the moral and legal implications of slavery. This decision deferred the responsibility of resolving the conflict over slavery to future generations, culminating in significant societal and political upheaval.
