Obamacare

The Affordable Care Act (ACA), also known as Obamacare, is a landmark U.S. federal statute enacted in 2010 that represents the most significant regulatory overhaul and expansion of coverage in the U.S. healthcare system since 1965. The law's major provisions came into effect in 2014, resulting in a roughly 50% reduction in the uninsured population, with an estimated 20-24 million additional people covered. The law also implemented delivery system reforms to constrain healthcare costs and improve quality, and slowed increases in overall healthcare spending, including premiums for employer-based insurance plans.learn more on wikipedia
