All the deficit-purchasing has not bought false prosperity, you're right; it's more accurately brought it forward from the future. And, like all interest-purchased goods or services the net gain is less than if it had of been paid for without the debt. The nation is quite literally and accurately borrowing from the future constantly, and at an accelerated rate. And this is not an investment in the future, it is not infrastructure, it is not education, it is simply cost of living like paying for booze that gives you nothing the next day.Wow, I think you are serious, but it's actually what I just called it 🙂 Optimizing GDP is what I said the nation isn't doing--which would be to use this debt to purchase equipment, build roads, power plants, invest in alternate energy (don't you dare find some pitiful little investment and say but look we are!). Most of the debt is going into gone today gone tomorrow expenses, from hip replacements to smart bombs.
