MarxistWell if interest rates for general consumers were 0 or near zero as well - there would be no reason not to take on massive amounts of debt - assuming whatever you were taking on that debt for would make you money in some way or you could structure the payments well enough not to destroy your standard of living. So it'd even make sense for a household lol.
It's still a bad comparison, though. The government doesn't have to make money on its money. Instead, it has to hope for continued growth of its tax base to eventually cover its debt - or, it can devalue its currency. Households may be able to claim future income growth which sort of compares, but households certainly cannot decide to cause inflation. There's a whole economic toolset available to the federal government that households simply don't have.
There's some (contested) evidence that the higher a country's debt load compared to GDP, the slower its economic growth. However, there isn't really any evidence of causation. In fact, Krugman argues the reverse of what you would expect - it's actually slower economic growth contributing to higher debt load, not debt slowing down growth.
