alt Hacker NewsIf there's hardly any individual desire, as you say, to fund the development of the poor then taxes in that pursuit are illegitimate under a theory taxation happens by the assent of the people (even if only roughly a majority or their representatives).
Given that most taxation done with the the advertised goal of helping the poor in Australia does happen with popular assent of individuals, I would theorize your position is false and that people do have some individual incentives to develop services offered to the poor -- for profit, humanitarian / charitable reasons, and a variety of other considerations.
> have some individual incentives to develop services offered to the poor
I never said that wasn't the case but historically that "some" was never sufficient. On average people are rational and selfish to a larger extent than they are altruistic.

Well the whole concept of an organized society falls apart if individuals can personally freely chose which laws to obey and which taxes to pay. You have to have a balance based on a reasonable consensus, otherwise you end up with totalitarianism or anarchy (and in that case the people who have the means and resources to do that will establish alternative power structures and will end up subjugating those who do not AND also outcompete those how have the means but are unwilling to do the same).
