"Now, of course, the great thing about the solar system as a frontier is that there are no Indians, so you can have all the glory of the myth of the American westward expansion without any of the guilt"

This quote by Sarah Zettel is a funny take on the concept of the American Westward Expansion. The idea of the Westward Expansion was a misconception of Manifest Destiny, where settlers moved westward to conquer the land and broaden the United States. This quote suggests that the planetary system is a brand-new frontier, and that it is a guilt-free method to experience the same sense of exploration and experience that the inhabitants of the American Westward Expansion experienced. It implies that because there are no native individuals in the planetary system, there is no guilt connected with the expedition and expansion of the planetary system. This quote is an amusing method of looking at the idea of exploration and expansion, and recommends that the solar system is a guilt-free method to experience the very same sense of adventure and expedition that the inhabitants of the American Westward Expansion experienced.
