If the world’s poorer countries could sell what they make at a fair price the lives of billions would be transformed. Yet every day these countries lose out on £1.3 billion – 14 times the amount that they receive in aid. Why? Because of the way that unjust trade rules help wealthy countries get richer at the same time as keeping the poor ones trapped. Our whole lives can fight this; from the way we shop to the power we have to talk to our politicians.
