Historically, debt neither increases forever nor collapses catastrophically. Individual sectors collapse, and new ones develop. In the early modern period, governments would simply refuse to repay their debts. Nowadays we have things like stock market crashes and mortgage crises.

We'll really be able to find out in the next 20 years. If it can survive the retirement of the boomer generation and the stagnation of China's economy, it will prove itself as almost entirely durable.

I think the true test of this system comes sometime in the next century when human population peaks. Expansionist policies assume growth (growing population) and don't handle shrinking or stable populations well.

Past performance does not guarantee future results :)

Neither do bald assertions with a smiley face.

We've been supposed to see hyper-inflation Any Day Now since like 2009. I'm sure it's just around the corner.
