Attacks to isolation, physical weakness can be useful in the early stages but then direct attack on poverty and powerlessness is necessary. Actions like helping the poor to organize, defend themselves and secure a better life are the most important. Trade unions or other forms of organization help also in this sense. Normally poor people are unorganized, illiterate, and it is often dangerous for them to try to have more power. The struggle against poverty has to be a struggle for political and physical power.
Outsiders can do many things to help.
Analysis of poverty and deprivations can lead to plan strategies for intervention. But analysis is the easy art. More difficult is to try to make deep changes in values and behavior. Accept that not everything we do will be welcome. Developers seen as saviors, not questioned.
