If you want anything done, in any branch of relief work, you will forget the word 'stupid' and be offended on others' behalf if it is used in your presence. It doesn't even take altruism.

As to multiplier/additive equilibrium, yes, causes need multipliers. What I disagree with is that causes will always benefit, linearly or otherwise, from hiring additives.

You start donating money. There appear hired people. The 'free' people gradually leave. You hire more to replace them. Other kitchens, which might not have lawyers in their staff, decide your kitchen can't play nice. You lose their cooperation.

Result: your own utility goes up, the kitchen's goes down.
