wsj: mobility is a force for good in rural india. really?

From WSJ:India.

Questions I have:

Is economic measure of sole importance?
Does the loss of a father, mother or child from the family have any long-term negative effect on the family or community?
Does the promotion of urbanization and globalization as a means to defeat rural poverty create homogenization? Is it important?
Are there more creative ways to provide the infrastructure and innovation necessary to allow the rural to stay within their communities?
