You're basically advocating for redistributing wealth from part of the global upper class to part of the global middle class and ignoring those experiencing the most pain and the most injustice.

I've explained repeatedly -- perhaps not in this subthread, so I'll reiterate -- that I'm only proposing reallocating domestic resources within the US, not resources which would otherwise be spent on foreign aid of any kind. I don't see how that can be harmful to anyone except (possibly) the extremely rich people from whom the resources are being reallocated.

(Will respond to your other points in separate comments, to maximize topic-focus of any subsequent discussion.)
