Constant growth in monetary terms doesn't require real growth. Most currencies are at least somewhat inflationary.

Bad loans, like broken promises, will always be with us. Sometimes you take a risk and trust someone, and it doesn't work out, so you're poorer than you thought. It doesn't mean we shouldn't take risks.

Bad loans usually are not about mistrust and deception, but about business risks that don't work out. Lenders very much expect that to happen, and charge interest accordingly.

Yes, agreed. The same is often true of other promises.

[wolverine876]

They are different.

When I get a business loan from a bank, I make no promise to pay it back. I promise to pay it back with interest if the business succeeds, and we agree that it might not succeed and they might lose their principal.

When I tell my romantic partner that I won't sleep with other people, it's an absolute promise.

Infidelity happens. So do divorces. Also, people get sick. People die. Society has procedures for these things.

There are very few absolute promises. Most contracts have some provision for what happens when they're broken. If there isn't one, it's poorly written.
