It is widely assumed that people in economically "advanced" countries do not differ significantly in how satisfied they are with their jobs. Since they are about equally productive, the reasoning is that they must produce things the same way, and so their work experience must be the same, too.
In fact, there are striking differences in job satisfaction within the West. The United Kingdom, with very low wages relative to the country's wealth, reports a pretty decent level of job satisfaction.
Yet Germany, with its fairly high wages relative to wealth, reports an undistinguished level of job satisfaction — below Italy and Spain.
