I've personally never done a survey. I don't doubt some "tax-exempt" NGO has performed a survey and published findings on the www. More important, charitable contributions to "think tank" operations always fund business activities such as publishing and P2P petitions (lobbying) to broadcasters and elected representatives. Some NGOs are established vendors in the supply chain of "manufactured consent." Not unlike faculty of educational institutions, their sole functions are to justify poorly conceived and executed public doctrines such as TARP and the NAFTA treaty. Setser is exemplary.

Diversity is the key to economic and political evolution.
