Ah, yeah, you gotta do that. Sorry for jumping to conclusions -- I shouldn't transmute the moral failings of our economic order into personal immorality so carelessly.
So I get the impression that you find something generally immoral about capitalizing on unequal distribution of information.
I can't help but be reminded of the time years back when an Internet rando told me, in all earnestness, not only that I should not profit from my knowledge of how to write saleable software and the sale of my labor in so doing, but that in a truly equitable society I would not be allowed to do so, because not everyone knows how to do that and it's wrong of me to privilege my own interests over those of people who lack the knowledge I possess. In that case there's a slight difference of detail in the origin of the unequal distribution, but the general concept seems very much the same.
I would be interested to hear whether and how you see a meaningful distinction between the cases, and in general to see some expansion on the nature of the moral calculus which moved you to make the comment to which I and several others responded.
