Yeah, there's plenty of criticism to level at Oxfam and similar, but this shouldn't be high on the list. Pending the revolution* - unless you have better idea - this stuff actually does save lives. In our annoyance - and, yes, the paternalism of this is almost blindingly annoying - let's not shrink from the thankless task of discriminating among evils, and choosing our targets-of-ire accordingly. Way too much noise on the list already (IMHO). (Of course, one man's noise is another's epiphanic ἀλήθεια, etc.)
