Politicians need to be very conscious of this when making their minds up whether to support CETA
Politicians are, and have been for a long time, very conscious of "this".
"this": the total elimination of democracy carried out under the guise of economic efficiency and while maintaining familiar democratic rituals, such as voting.
The main job of politicians under our current system is to oversee this dismantling of democracy. Key to this task is to preserve a facade of democracy for as long as possible, while simultaneously cementing the pillars of global corporate autocracy. Trade treaties are one of many components in this sneaky transition. It allows policy makers to implement anti-democratic measures with the pretext that their hands are tied by the terms set by the global treaties. If these treaties did not exist, our politicians would have to invent them: again, the treaties are NOT the reason for the undermining of our democracy, they are the means (one of them) through which the last vestiges of real democracy are being eliminated.
The reasons go deeper; among them is our loss of political consciousness.
There are no quick remedies to this tragedy, although while we still have some sort of voting available to us, we may as well use it to support candidates who clearly articulate a strong critique against these trade pacts. In the US, Bernie Sanders and any Green Party candidate are good examples. Hillary Clinton, on the other hand, is just like any other Republican.
