Favors, markers and promises are humanities’ first virtual currencies.
They’ve gone digital recently, as Jack might redeem his marker via a WhatsApp or WeChat text message.
Favors and promises aren’t financial obligations per-say. They’re moral debts that can be redeemed for things of intrinsic, monetary, social and/or actual value. Now, here is where things get a little weird. The thing about “money” is that it doesn’t have any value. It’s actually a reflection of a moral debt. Hence why the US dollar is backed by the “Full Faith and Credit of the US Government” and not say, gold or wheat. You believe...that people will feel obligated to pay taxes and in turn the government will collect these social obligations (aka favors) for the good and benefit of The People. This moral obligation is part of that “Debt to Society” you’ve heard so much about, are obligated to pay, but don’t recall actually signing up for.
