I see that no one has taken finance here ... Debt increases return on investment. That is w/o debt we'd have to fund all gov't expenditures with tax income. Since that is a lot lower, our ROI would be a lot lower.
Government sponsors many things that are usually under produced in cap. market (tragedy of commons) - research, infrastructure etc. If you cut funding, a lot of stuff won't get made - Internet, Google etc.
Also take a look at the debt load of the richest nations - U.S. is right in the middle in terms of debt/gdp.
heh, maybe you need to revisit the finance course you've taken. Debt does not increase ROI, at least not all the time. You only increase ROI when the investment your made with debt has an ROI > cost of borrowing.
I am fine with US debt as long as
1) government justifies the spending with quantifiable return that's > cost of borrowing.
2) interest payment is not too high and in the worst case scenario, like a prolong depression, the goverment can still meet the interest payment to avoid national default. Remember interest payment of your current debt is fixed liability and your revenue depends on your economy.
Simple things, just like any coporate finance 101 course you would take on simple company debt structure.
I don't see the US government meeting criteria #1 and states like Cal is already failing criteria #2.
