The final issue to consider before actually writing your bill is how much your bill will cost. The 2020 federal government budget was $4.789 trillion - that's $4,789,000,000,000 and a 25% increase from 2015! Actual 2020 spending totals due to the pandemic will be significantly more. Needless to say, that's a lot of money. The government spends it on lots of things--on programs as large and popular as Social Security, and on activities as small and unknown as repairs to the National Zoo. The COVID-19 vaccine will be distributed to citizen at tax payers expense. Together, these programs are what make up the federal budget. While the budget is written by the president, it must be approved by Congress.
The federal budget is a plan for how the government spends money and for how the government pays for its activities. Each year Congress and the president must decide which programs will be funded and for how much. For example, how much should we spend for unemployment relief, defense, national parks, the FBI, medical research, Medicare, and meat and fish inspection?
