Well my point is bit different - Incentives through Inflation need to be optimally directed so that people are motivated to contribute positively. If we just donate which induces lethargic behavior, like what is the need to work hard or intelligently if I get my basic needs fulfilled by donation, then we are doing more harm to those whom we donate as well as to entire society.
So wealth redistribution should be attached with an objective to promote positive and constructive behavior.
