LDH:
It's really even worse than that. The Watchtower is represented in those same countries where poverty and sickness abound. Yet, nothing is done to alleviate the suffering right around them. Instead, they exploit the people to support them and their ministry. The only help offered is within the congregations...and even here, it is not the Watchtower Society...but individuals in the congregation.
At least some of the other missionary groups are actively involved in bettering the lives of people. Many are trained nurses and doctors. The whole lesson of being a good neighbor is illustrated by Jesus in his parable of the Good Samaritan. He saw a fellow human suffering...and he did something to aid him. But Jehovah's Witnesses in these countries are more like the Priest and Levite of that same illustration.
