Several Catholic organizations have been doing this for years. In concept, a good, Christian thing to do. However, it needs to be done in a frame work that allows for those recipients to pursue self-support and self-worth as the eventual goal. Charity is one thing, welfare, another. Part of the problem is that depending in what country the “poor” live, what is causing them poverty? Is it government economic policy, etc. The world will always have it’s poor (Christ said so, although he may have spoken in both economic but I think primarily in a spiritual sense). As for the “rich” parts of the world supporting the “poor” parts, the rich are tottering on economic implosion due to massive indebtedness and corruption, we may all be in the same soup before long.
The organization “Food for the Poor” focus its charitable work on collecting donations for low-cost food and basic housing in places like Haiti, but also solicits donations for things like sewing machines and farm animals so that its aid recipients can begin to develop some self-reliance.
It strikes me as a good model, and one that could be expanded. And it embodies a fundamental aspect of Christian charity - that it be individual and voluntary. One place where the Catholic hierarchy went very wrong in America was buying into and supporting the liberal idea of charity - that it be collective and coercive. That’s never worked in any society (see, for example, communism) and it sure ain’t working here.
