I don't want to take away people's purchasing power now, I want to sap away their purchasing power over time. If I do that I encourage them to take their money and invest it into a factory producing widgets instead of squirreling it away into a bank. Inflating the value of money gives an unfair advantage to people who use their money to improve the world by producing things. Being in debt sounds like an OK trade to me so long as it's not pathological.
