But it's a contraction from an artificial high, and the contraction wouldn't be permanent. That's the point your missing. Constant deficits will never cut the debt. It's like fighting withdrawal symptoms with more booze because you think feeling ill can't result in walking straight again.
Or how about a household example. You take out 10 credit cards with 5k limits. You spend all 50k in 1 month. What a great month, it felt great. Next month, you can't spend for shit because you've maxed out your cards, all you can do is barely service your past extravagances plus interest incurred. What a shitty feeling month. Your solution: perpetually take on more credit lines to pay off old credit debt? That's called a ponzi scheme, and it ends in a liquidation of your belongings and a total waste of loaned money that could have gone to producing, not consumers.
