Free trade helps the poor AND the rich, because it increases the “supplier space”, and this increases the competition, and that decreases the prices for the supplies for poor and rich alike.
All these “free trade” laws are not that at all. They are crony protection agreements. The evidence is in the numbers of pages. Free trade requires one simple declaration:
“All tariffs will be abolished in trade between the parties to this agreement. Period. FULL STOP.”
All those such treaties signed in the past few decades, NAFTA, TPP, GATT/WTO, they are all treaties that establish governing institutions with enforcement. This means they are steps toward the world government infrastructure the plutocrats and oligarchs have been planning for in lo, many years before.
