In addition to attacking our rights and undermining regulation of business, TAFTA aka TTIP would lead to only a tiny amount of economic growth.

That growth would not go to workers, because treaties like this give business more power to drive down wages and hurt working conditions. The plutocrats would grab all the benefits, and more, leaving workers worse off than without the treaty.

TTIP stands for "This Treaty Is Plutocratic".
TAFTA (its other name) stands for "Turn All Freedom To Ashes".
