Globalization has increased connectivity between countries but may not reduce inequality within poorer nations. While trade theory predicts inequality will fall as developing countries enter global markets, many have actually seen inequality rise. This is because multinational companies in poorer countries often employ skilled labor, raising their wages, but unskilled workers do not receive the same opportunities and productivity gains. New theories suggest globalization can boost wages for skilled workers but limit wages for unskilled labor, increasing inequality. Despite allowing closer economic ties, globalization has also been linked to growing inequality in some developing nations.
