The National Debt, Perspective...

In the last 7+ years the national debt has doubled to nearly 19 trillion dollars. Like most candidates, both are currently talking about new programs/initiatives, etc that will cost money but offer very little substance as to how it will be paid for. Thought maybe this could help people put into perspective the magnitude of what some of these big numbers actually are. When I hear tax increase it just makes me wonder when enough is enough. We can't spend our way out of debt, so why would the government think they could.
