You may think this is some form of conspiracy theory, but there's very strong evidence for it. I would recommend starting here...
Also, in general, whats wrong with multinationals having a strong influence in the present world? They are the modern day 'kings' replacing their medieval counterparts. Of course I am not arguing for blanket powers for them at all. We of course have checks and balances like regulators/auditors/politicians. Even take the example of #Brexit, it happened didn't it? If corporations had absolute power it would not have.
The point is what's good for society in the long term? Who knows best? No easy answers. But I am willing to err on the side of doers (with checks and balances of course) rather than pure career politicians.
Unfortunately, with euroskepticism strong also in countries like France, it seems improbable that we are going towards an U.S.E. any time soon. But if Britain were not in the EU in the first place, maybe we would have achieved it already...
