The global exchange that began with Columbus's voyage introduced new food crops and ideas that changed the world. The Columbian Exchange brought potatoes and corn from the Americas to Europe, fueling population growth. This eased food shortages and allowed more people to migrate. New economic ideas like capitalism and entrepreneurs arose alongside inflation and price increases. Joint stock companies helped fund overseas ventures by pooling many small investments and sharing profits or losses. Over centuries, this global contact shifted influence from landowners to merchants and a growing middle class, though most workers remained poor.
