Here is a brief example (below) from the World Bank's latest Development Report. They group countries into several categories by GDP/capita: Low-Income ($935 or less), Low-Middle Income ($936-$3,705), Upper-Middle Income ($3,706-$11,455). Other outcome measures show similar results.
This probably is a complex problem and it is not my field of research. However there seem to be at least two major dimensions: 1.) Societies that have fallen apart (e.g., the horrific problems with anomie-linked alcoholism and drug use, etc. and the collapse of the public health system and life expectancy in the Russian Federation) and poor societies that never came together (some African countries); 2.) Discrimination, which remains ubiquitous. (It undermines public education for women; it is one of the greatest sources of violent conflict, especially involving ethnic groups, etc. Often it expresses a human-sustained scarcity (of respect, in systems of hierarchical status) that is more usefully addressed by psychological change rather than money.)
Just a suggestion: This might be a good time for WAAS to convene a strategic planning group of development-oriented organizations to focus on renewed progress for human rights - specifically, an End to Discrimination campaign. [There is a good, "Yes, We Can!," example in the US, in the election of a Black President against the background of a civil rights movement.] We ought to find ways to use the new communication technologies to create the shared expectation that this, the end of discrimination, is the natural agenda for cultures and political systems worldwide. If a breakthrough is possible, humankind can get revolutionary progress in the next several years even if GDP/capita isn't available as the engine.

Good Societies
A variable that I believe is relvant for measuring a society is the level of emphatic understanding and respect molding the interpersonal relationships, the level of social support and solidariety exanged and the promotion of the development of human potentialities.
Which other varables that can be used for calculating the level of the so called national wellness product ?
