What does the woman do?

W: Good morning, Professor Sherwood, Thank you for accepting our interview. You’ve been doing re search on happiness for many years, so I’m sure you have some interesting information to share with our audience.
M: Good morning. I hope I can answer your questions.
W: Are people in rich countries happier than people in not-so-rich countries?
M: Well, I would say there is a relationship between national wealth and well-being. In other words, the economic wealth of a country does appear to reflect the overall well-being of its citizens.
W: Does it mean that rich people in a country are happier than poor people?
M: In some poor Countries, satisfaction with one’s financial situation does affect happiness. But once people are able to afford the basic necessities of life; having more money doesn’t necessarily make them happier.
W: What about rich places like Europe and United States? Are income and happiness related?
M: Very little. Rich people are only slightly happier than the average citizen.
W: I’m always wondering whether winning a lottery can bring happiness.
M: Well, as a matter of fact, various studies show that lottery winners only get temporary joy.
W: I guess wealth is like health. If you don’t have your health or if you’re extremely poor, you will be miserable.
M: Yes, that’s true. Happiness is wanting what we have rather than getting what we want.
W: That’s a nice way of putting it. In your opinion, do people become happier as their countries be come richer?
M: Well, if I take the case of the United States, from 1957 to 1996, the proportion of people who said that they were very happy declined from 35% to 30%. But during that same period, the average income per person in the United States doubled.
W: So, you mean that a steady increase in a country’s prosperity does not mean an increase in its people’s happiness.
M: That’s right.
