"But how can you ask other people to lower their salaries, without giving your life to charity first? Isn't it hypocrisy to call for change for everyone without turning over your own income?" Morality is not saved by any individual's efforts to do charity, a pocketful here, a handful there. Charity is the vice of unequal systems. (I'm only repeating Wilde's "The Soul of Man Under Socialism.") We shouldn't have to weight whether our money would do more good in a destitute person's pocket, or our time do more good if we ladled soup to the hungry, or our study do more good if it taught reading to the illiterate. It always, always would. Because it is hard to give up your money, however, when not everyone else does, and hard to give up your time when not everyone else does--and nearly impossible when you have less time, and less money, than the visibly rich and comfortable--and frankly, because it's not often a good idea to give up your true calling or your life at all, our giving is limited and fitful. It can never make a large-scale difference.
