Why is paying off debt so important when long-term interest rates are so low? For example, the yield on 30-year Treasury Inflation Protected Securities is currently 0.92%. If the government sold these bonds to invest in long-term infrastructure projects, wouldn't that boost the economy enough to outweigh the increase in debt?
Is it necessarily a burden to have debt if it is coupled with infrastructure assets? Don't you need to quantify the debt relative to the assets in order to say whether it's a burden or benefit?
