I never understood how this morality worked. The problem I see with this view is that you are double counting the value of money.

• You work an hour and get $10, but the employer just killed $10 worth of people by hiring you instead of sending it for aid
• You buy a latte and just killed $10 worth of people by hiring you instead of sending it for aid
• LatteShop pays LatteBoy $10 for an hour of work and just killed $10 worth of people by hiring him instead of sending it for aid

The $10 doesn't leave the system and everyone who touches it just killed a whole slew of people because they sent it somewhere other than aid. Why are you carrying the moral burden?

Even if you did send it to aid you can blame them for charging $10 for their work instead of $9. (Or whatever company that is selling the rice, nets, stoves, filters, bottles, condoms.)

You could even blame the person receiving the aid for using the aid instead of giving it to someone less fortunate. Or using less of it. Or selling it for $11 and putting the extra money back into aid.

Somewhere in here something goes horribly wrong and it gets ridiculous. Where did I misstep?

EDIT: I really don't want to give the impression that you shouldn't give money or help people less fortunate than yourself. I think these are great things. I just don't understand the jump from "I bought a latte" to "I killed people."
