Lol, the guy who clearly doesn't understand debt/GDP ratio tries to tell me to take an economics course. What a joke. By the way while we're on the topic of economics, feel free to send me some links to some who feel the same way about the debt ceiling as you do.
Now, back to debt/GDP ratio. What I was trying to get you to figure out for yourself in pointing out the denominator in debt/GDP ratio is that government spending is a component of GDP. When you cut government spending, you cut GDP. In a depressed economy such as ours, the evidence strongly suggests that fiscal multipliers for deficit spending are greater than 1. This means that stopping new deficit spending makes our debt situation WORSE, not better.
Hence, if you want to control our debt situation better, you raise the debt ceiling. (not to mention the other bad effects like mass unemployment, etc).
So in the future before telling someone to take an economics course, you might want to brush up some yourself.
