At one time Native American businesses were mostly dependent on tourism. The twentieth century marked the opening of numerous casinos on Indian reservations across the United States. Today these and many other Native American businesses—both on and off the reservations—are thriving. Despite powerful setbacks including a worsening economy, many Native Americans have managed to turn adversity into achievement. From office supply companies to restaurant chains, these businesses make up a growing part of the US economy in the twenty-first century. Many Native Americans who have enjoyed professional success now work to open doors for other tribe members to create better lives for themselves and future generations of Native people.
