Parfit objected that the pledge should not be called 'giving' because Westerners do not deserve their fortunate circumstances and the wealth was never truly theirs to give, and that '10%' is not 'what we can' since people could clearly give far more—criticisms reflecting his literalism, set against the marketing reality that 10% is psychologically doable and thus effective.
