It’s not a matter of scale, it’s a matter of lifetime. You can’t roll over a loan indefinitely because you will at some point die and lenders will factor that in to their calculations. But even in the small, plenty of people take out mortgages and spend WAY more than they were earning and do very well out of it. The breaking point is if you expand your debt repayments beyond your ability to service them. And, because growing economies and inflation are both real things, an ever growing debt is not only possible but desirable. As long as you can invest in things that grow the economy like libraries and benefits for those in need, you’ll be fine. Btw, read a UBI study sometime. You’ll find the actual research into just plain giving people’s money does not match the naive econ101 theory.
