How Much Increasing Debt Is Too Much?

Debt allows a country, or a human being or corporation to buy something now that they don't have enough savings to buy. So what happens is they borrow money and buy this thing. And so it over states deman in short terms and will dramatically lower demand in the future. It takes somewhat close to, i don't knobut 50 an incremental debt to produce a buck of incremental g p. That's unsustainable. I know just as my mother and father taught me, this is kidieoy.
