As an American who has travelled throughout the world and started out life in a poor home (by American standards), I know that the majority of Americans can afford luxuries, even some Americans who are considered poor. When compared to global standards as opposed to country standards, the word "luxury" has a different meaning. It is not an extremely expensive car,rather it is just a car that woks. It is not a big fancy house, it is a house that only you and your immediate family occupy. By this global standard, we are a wealthy country with many luxuries. But by American standards, what we call luxuries are available only to a minority. The more affordable an item becomes to the masses, the more quickly it moves from the luxury category to the ordinary category.

If it's the majority, then it's no longer considered a luxury ;)

I think most people can afford luxuries but only modest luxuries. Typical middle class people can afford small luxuries. But nothing like a lambhorgini, or Porsche. i.e. we have a large middle class but not too many extremely rich people.
