No, I don't own a suit at all, but there are many other possible examples.

I gave the Unger example at the end of my post.

It's true that, by the point I have made my own life as unpleasant or unsafe as that of the people I am trying to help, diminishing marginal utility means I can definitely stop without guilt. Realistically, I am not going to go that far. I am not a saint, and if I accept the obligation but stop giving earlier I will feel guilty and hypocritical and awful about doing so.

I agree with Pablo.

My post is relevant to triaging with respect to different altruistic efforts.
