Ronald Reagan and Barack Obama are two of the most significant presidents in the history of the United States of America. Both served as leaders during times of economic uncertainty and implemented economic policies that had far-reaching effects on the country's economic landscape. Ronald Reagan’s “trickle-down economics” was a cornerstone of his economic policies during his presidency from 1981 to 1989. His policies were centred on the idea that by cutting taxes on the wealthiest Americans, it would stimulate economic growth and create more jobs. On the other hand, Barack Obama's Affordable Care Act was focused on providing access to affordable health care to all Americans, regardless of their income level. This paper seeks to compare and contrast the economic doctrines of Ronald Reagan and Barack Obama, with a focus on their ideologies, policies, and impacts on the American economy.
