In United States public policy, supply-side progressivism is a political ideology that emphasizes increasing the supply of essential goods and services, such as housing, healthcare, and higher education, in order to make them more abundant and affordable. Supply-side progressives believe that some regulations artificially restrict the supply and drive up costs of essential goods and services, while other regulations, such as antitrust law, need to be implemented or enforced to encourage market competition and innovation. They also advocate for more investment in research and development for technologies such as sustainable energy sources in order to increase abundance and reduce costs over time.[1]
