Jim360 it is the military industrial complex that covers it up. It's a sustained campaign for social, economic, cultural and military control over us all by an elite group of sickeningly wealthy families e.g. Rothschild, Rockerfella, Morgans. One or two you may have heard of but did you know for example that genius inventor and scientist Nicolas Tesla genuinely discovered a way to transmit electricity through the atmosphere, directly from the plant to consumer's homes, at the turn of the 20th century and wanted the technology to be available to all mankind. He submitted a patent to his financier, J.P. Morgan (a wealthy banker) to be filed at the patent office but was rejected by his boss and all funding stopped. After such an amazing, world changing, universally beneficial discovery one would think that it would advance mankind into a new age, but J.P. Morgan had a monopoly on the copper used in wires to transmit electricity via cables being build all over the U.S.
This is an obvious case of greed over public benefit but it's never discussed or re-visited by mainstream media due to the stranglehold these's trilionaire have over distribution of information.
Therefore you're correct that a body of elected members of the public couldn't conceal it from us, but a dominant and established elite that control most national banks, utilities, fossil fuels and media most certainly could.
Whatever you think of me and this information I've confronted you with, at least respect the fact that I hold this opinion and it is mine to share in forums like this. I urge you to look into it in your spare time, it's truly shocking and there's mountains of evidence to support the claim.
