Congress uses (fiscal, monetary) policies to attempt to maintain a stable economy. This includes making changes to taxes and government spending.

Fiscal policies refer to the government's decisions on how to collect and spend revenue, such as through taxes and spending on programs and services. Congress can use fiscal policies to influence economic growth and stability by adjusting tax rates, increasing or decreasing government spending, and creating or cutting various programs.

Monetary policies, on the other hand, are decisions made by central banks, such as the Federal Reserve, to control the money supply and interest rates in the economy. By adjusting interest rates and implementing other monetary tools, Congress can influence inflation, employment, and overall economic growth.

Both fiscal and monetary policies are tools that Congress can use to try to keep the economy stable and growing, though they each have different methods and impacts on the economy.
