Let me take a stab at this.
Debt isn't bad. It's only bad when it destroys you. In fact, it makes economic sense to take on as much debt as you can handle.
A little known fact was after the revolutionary war, America was broke. States could not pay back the debts they had written and were considering telling their veterans and Europe: Sorry, we can't pay you back because we don't have any money! This was what everyone expected, actually. However, Hamilton's goal was to set up a national debt. Why? Isn't debt bad? No, it isn't. Hamilton assumed all the debts of the states as part of the national government and began to pay them off.
Why did he do this? Debt is momentum. A goal, a constant reminder to keep things going. If people had no debt, as those in other countries, they have no incentive to keep living so to speak. People in other countries are also not as productive as Americans. The huge debt Americans take on is a constant incentive, a constant reminder to keep going and to pay off their debts. Otherwise, what's the point in it all?
