How does the tenth ranking in the world for the economy of Switzerland manage to have the 2nd highest nominal gdp per capita?

Per my information Switzerland has the 10th largest economy in the world, with a gdp of about 800 billion dollars. But at the same time it has a gdp per capita of about 90,000 per year, or about 7,500 dollars a month. <br><br>In contrast the United States is the largest economy in the world with a gdp of 25 trillion dollars. Yet it has a gdp per capita of only about 60,000 dollars per year. <br><br>How does Switzerland manage to have such a high gdp per capita given that its economy is so much smaller than the US?
