Today, many trade agreements compel developing countries to restrict unions and worker protections. And because globalization allows companies to move easily across borders, employers can chill their workers’ wage demands by threatening to pull up stakes and move somewhere cheaper... The point is that wages are not somehow naturally low in the south – they have been made low by design. Wages are an effect of power... There’s an obvious solution: a global minimum wage. If capitalism is going to be globalized, it makes sense that we should globalize the rules and standards that protect people from it as well.
