Apologies if this was asked before…
As I understand Objectivism, I must act in my self interest, anything which hinders this I must regard as evil.
Suppose I give 100$ in charitable aid to some tribe in Africa. Over my life span I will receive a total return of 1$ for this investment. I have essentially burned 99$.
Is what I did evil? If I burned 99$ anyway it would be, would it not?
First off, you are mistaking “money” with “self interest”. O’ists consider money to be EXTREMELY important - but contrary to popular misconception, neither we nor Ms. Rand considered Money as the ONLY thing of importance. Money is simply a means of trade - and the reason it’s so important is what it represents and what we can do WITH it, not the money itself.
Giving $100 to a tribe in Africa could be a perfectly moral act on your part, even if you never see $1.00 back, *if* it contributes to making the world into the way you want the world to be.
If your $100 goes to the tribe in the form of food and/or clothing, and enables them to stay alive for a short while longer, but doesn’t encourage them or help them to become more productive and more able to stand on their own feet, well - you might as well buy a few bottles of liquor for the local wino for all the good it will do - you’ll just be enabling bad behavior, and that, in the long term, is against your own self interest - you’ve helped create a world of mooches who will look to you more and more for their own sustenance.
On the other hand, if that $100 goes to the tribe in the form of a pair of sheep and the education needed on how to raise them and produce wool, and the tribe becomes a productive shepherding tribe producing some of the finest wool in the world, you’ve helped to create a world of producers - of equals - of peers - of people with whom you can live together and be free of dependency except those which you choose.
In other words, your $100 charitable gift can be moral or immoral - and it is up to you to determine which it will be and the moral course of action is to ensure that the gift is given with moral intent.
