ELI5: Explain Like I'm 5


Keynesianism is a theory of economics that was created by a man named John Maynard Keynes. It states that governments should use certain policies to help the economy grow and protect people from poverty. To do this, governments use taxes, borrow money, or change the amount of money in circulation. This helps people buy the things they need and can help create jobs. So, by helping people and businesses, governments can help the economy stay strong and make sure everyone has enough money and jobs.
