How can the fiscal policies of a country influence the finances of a single individual?

 " When the economy is tight with high unemployment and poor circulation of money: Policy can be changed to allow more government spending which stimulates employment and growth. During the great depression, congress wanted to cut spending to balance the budget. Nobody had any money to spend and the economy got worse. Finally FDR started some public work projects that got many people working. When people have jobs they spend money and that circulation is what has kept our country booming for mostly 70 years.
