As a single jw, I helped several people with money and food, provided transportation. Growing up there were some jws that helped us out financially to go to the conventions, provided transportation to the meetings, grocery shopping, and working on my car when I was a young adult.
Most jws who do that don't publicize it and the recipients tend not to advertise either (out of embarrassment, hard to say).
Yes, I have seen many individual jws help other jws out financially, etc, but because they were that kind of person, not because they thought it was part of jw policy.
