From the medical cartels point of view it seems they only want more profit, and they know that nutrition and natural cures make people healthy, which is not good for profit. Then another group of world leaders are thinking about both global resourses (both ownership and distribution) and difficulties in controlling large masses of people. Already around 1930 it was up in congress in US. Scientist warned against the population getting too big and made diagrams on the global population "explotion" all the way into the 2010 and beyond. They decided to try to change the scenario but the records on how they would do it I haven´t found. Probably it´s focused a lot on biological weapons. On the other hand it´s so difficult to find the right information and prove it so it´s a catch 22 situation, although proof of biological weapons and attempts to control nutrition intake for the population is very obvious. It´s the same thing all over the world not just US. They have been fighting in court about it recently here in Europe against the german medical cartel (for the right to get nutrition in Europe) and it seems to be an ongoing battle.
