Las Vegas is not like other cities. No city in history has so explicitly valued the needs of visitors above those of its own population. All its growth has been fueled by tourism, but the tourists haven't spoiled the "real" city; there is no real city. Las Vegas doesn't have fascinating little-known neighborhoods, and it's not a place where visitors can go off the beaten track to have more authentic experiences. Instead, the whole thing is completely self-referential; the reason Las Vegas boasts the vast majority of the world's largest hotels is that around thirty-seven million tourists each year come to see the hotels themselves.
