While on this topic of "studies", at a minimum, there is one clear fact that any genuinely interested & health-conscious people must have committed to memory when it comes to what we call or think of as studies.
The industry of studies is not unlike any other large-scale commercial enterprise that is corrupted & influenced by a compmlex albeit cohesive system of racketeering. There are layers upon layers in this system we collectively call our establishment. With few exceptions, most commercial enterprises exist in one form or another as a beneficiary to this system of layers of sub-systems. At the low end of the system, commercial enterprises may not yet even realize that they exist in such a criminal hierarchy. Be this as it may, the racketeering sub-system itself is comprised of it's own numerous layers and bit players as corrupt if not more than those wielding control above them. Herein will be found even the likes of, effectively, a Tony Soprano who happens to be the don of the garbage-collecting industry or meat/butcher shops or stripper bars or cocaine/heroin distributor in his particular segment of power and influence in New Jersey. During the past 60 years of evolution in America's combined racketeering in medicine & higher education, David Rockefeller wore many hats as don of this, that and the other syndicate of corruption, to include don of America's Medical / Scientific Study Industry. Just from a symbolic view, it does seem somewhat fitting that an aristocrat bearing the initials DR would come to be a long-serving csar of things medical & educational in America. He is now rather aged and likely has long-since passed on this one baton to some other don. I suspect that as the force of malign influences may strike him and his fancy, his crooked fingers proably still are permitted access to many of the buttons of our establishment system.
