How is it a great deal for the Germans when they are not going to get repaid?
So you would lend money to someone who’s not going to repay you?
If the Greeks stop repaying them, that forever money spigot gets turned off. But if the Greeks keep paying it off, it's the best deal a banker can have. It's very Mafia-like to loan someone an amount they can't pay back and thus own them, but have to keep making payments on that forever-loan.
