It doesn’t work to just ask, what effect would it have on the world, if everyone like me made decisions according to this rule. You also have to ask, how would the rest of the world respond.

If you give charity, you call into existence those charities who take advantage of free money being given out. Your behavior is always simultaneously both responding to a niche and also creating niches.
