Culture evolves over time and is largely impacted by improved standards of living and exposure to other cultures  Virtually all cultures around the world have changed radically over the past two hundred years; if a government takes action towards "preserving" an indigenous culture, it is interfering with the group's ability to mold their identity to fit the modern world on their own terms. For example, the Australian and American governments have tried to appease native groups by offering land for reserves where they may lead a traditional lifestyle. Native individuals, however, often do not want to live in isolation, and would rather adapt their culture to an urban environment where they can have a higher standard of living.
