My (Somewhat Pessimistic) View on the Economics of the United States of America

What comes to mind when I think about economics is failure. You’re probably thinking “how pessimistic” right now. You’re absolutely right. This is very pessimistic, but true. The economics in the US has been going downhill for a long time. Well, that’s what most people say. That’s all I know. I’m 12, how do you expect me to know about the great failure of a country I live in. Oh well. I’m moving to Canada or Britain as soon as possible. I'm not as clever as the Doctor.
What is your view on America's economy?
