Here's an analysis/breakdown of the passage's main points:
1. Conclusion/Main Point: Human indicators provide sounder measure of a nation's progress than GNP (Gross National Product,) which is supported by many political economists as soundest indicator.
2. Premise 1: Economic health as measured by human indicators does not always reach a level commensurate with per capita GNP (all of this goes directly against PE viewpoint.)
3. Premise 2: GNP often presents distorted picture of the wealth of a nation, as it frequently obscures a lack of distribution of wealth.
4. Some nations have recognized that their efforts are better directed towards achieving salutary human indicators, without which the well-being of a nation may be endangered (whereas GNP can lag or remain stable without endangering nation.)
