The standard of living of the United States is among the highest in the world. By measures of material wealth such as "per capita income" or [per capita consumption]
?, the
United States ranks higher than all but a handful of small city-state countries. Of course, [standard of living]
? should be measured by more than just those factors: other factors include legal structure (freedom of speech, freedom of the press), crime (which is higher in the United States than in many other high-income countries), etc.
Concerns may also be raised as to whether averages are the best way to compare the standard of living, as opposed to a Pareto index of some sort. Some oil rich countries like Iraq may have a high average level of income, even though ordinary people aren't doing any of the consuming! Measures which take into account, in some fashion, inequality, should
probably be considered.
