Shrug, you call it dangerous debt, I call it having craploads of T-Notes out there with extremely low interest rates and it's basically free money. It has to be paid back? Kinda, except that people keep buying treasury notes which we can use to pay those.. Call it a ponzi scheme if you want, not really accurate but maybe close.
What's going on is better than trying to not spend money and have the country contract further. We are taking on debt, but in that regard we are still trying to expand the country and not get into a Japan situation.
I find most people who spout off about the debt/deficit really don't understand how it works on such a country/global scale. It's not as simple as "debt is bad". Infact, it can be quite the opposite. If you are able to make more money/growth from borrowing money, then you are better off. With interest rates at virtually 0 the past 4 years, this is the case we are in. Better to be overspending to make sure we get out of the situation we are in then penny pinch ourselves into more contraction.
