If you allow the rich to establish treaties that prevent nations from exercising sovereign power to bring those same rich people in to line, and you do it in private preventing the citizens/subjects from even knowing the details of the regime you intend to impose then you're operating well outside anything that can be described as democratic. TTIP seemingly intends to go further still, not only preventing nations from exercising sovereign powers against corporations but allowing the corporations (which are really proxies for the plutocrats) to exercise equivalent powers over those nations.
We've seen these sorts of powers in use by tobacco companies suing countries for trying to improve citizens health.
It's fantastic capitalism - profit above environment, profit above health, profit above morality, profit for the few against rights and freedoms of the many.
