Compound interest is essentially the mind worm we plant to get people to let us spend their money for them. The problem I see with it fundamentally is interest changes the conversation from "there's a thing that needs to get done" to "lets make some money".

There's a lot of pointless/ultimately destructive ways to make money. Precious few to get dpne what needs to get done. And I wholeheartedly believe much of society has forgotten that "what is profittable" != "What needs to be done".
