The purpose of this legislation, known as the Default Prevention Act, is to ensure that the United States government can meet its financial obligations, specifically the payment of interest and principal on its debt. This is crucial to maintaining the country's creditworthiness and financial stability. The key provisions of this act outline a structured approach to prioritizing payments when the government's debt reaches its legal limit. It establishes a tiered system for obligations, categorizing them into five tiers based on their importance.
