For David, it's basically about how corporations are usurping government and making policy to benefit themselves and the people behind it. Some known, mostly shadowy figures lurking in the background.
TPP is a good example. Countries are enticed to join only to find under the agreement their governments can be sued by U.S. corporations if they introduce laws unfavourable to the corporation. Some seriously unbelievable stuff. I really suggest everyone read it. Twice.
