Why did the US embark upon the large policy?

The U.S. embarked upon large policy initiatives primarily to address significant economic, social, and political challenges. These policies aimed to stimulate economic growth, enhance national security, and respond to public demands for social justice and equality. By implementing large-scale reforms, the government sought to stabilize the economy, improve infrastructure, and expand access to education and healthcare, thereby promoting overall societal well-being. This approach was also influenced by global events and the desire to maintain competitiveness on the world stage.
