Now there are many traditions around the world that works. Most cultures have man+women=family (as opposed to some form of polygamy), and there is reason to suspect this is important even if it isn't "in" to study why. (it isn't clear which non-traditional forms also would be fine and which would be a disaster)
Saying "poor are poor because they deserve it" is an accusation that I hear a lot more than I hear people who believe it. Some do believe it, but most accused of it do not and have better explinations of why they do things that the accusers don't like.
