Following up on my last comment, while JWs could indeed do some real charity work, their concept of teaching people to work for themselves and take care of themselves isn't wrong at all.
JWs can be poor, but usually, their houses will be clean, and will learn to cook decent meals on a low budget. My point here is that charity is a temporary answer and JWs do understand that.
Still, they could be helping people a little more.
For instance, in Gatineau, when there was a flood and hundreds of citizens were filling sand bags, they were out there preaching door to door. That is having their priorities at the wrong place.
