Public sector corruption can discourage investment, reduce efficiencies, unfairly alter market forces, and generally reduce prosperity in any country. According to Transparency International, Denmark ranks as the least corrupt country in the world. Denmark has a service-based economy with one of the most generous social security systems in the world. Wealthy countries like Denmark tend to have healthy populations. Life expectancy at birth in the Nordic nation is 81 years, nearly nine years above the global average.

Saudi Arabia is one of several nations in the Middle East that owes much of its wealth to oil. The Kingdom controls roughly 16% of the world’s proven petroleum reserves. Petroleum exports account for almost three-quarters of the nation’s exports and for 42% of its GDP. Saudi Arabia’s reliance on oil to sustain its wealth has meant that the lower oil prices over the past five years have taken a toll on the economy.

The Netherlands is one of the few countries in the world with a GNI per capita of over $50,000. Part of the Netherlands’ wealth comes from its highly productive agriculture industry. The relatively small nation is the second largest exporter of food in the world, behind only the United States, which is more than 250 times larger in terms of landmass.

Ireland was one of the hardest hit economies during the global financial crisis of 2007 and 2008. But the European nation has rebounded in the following years, recording GDP growth of over 7% in 2018. Trade is a major component of the Irish economy, with the total value of exports and imports in Ireland in 2018 being worth more than double total Irish GDP that year.
11. United States
> GNI per capita: $55,351
> 2018 GDP: $20.5 trillion (1st out of 208 countries)
> Population (2018): 327.2 million
> Life expectancy at birth in 2016: 78.5 years
The United States is the largest economy in the world, yet it does not quite break the top 10 for GNI per capita. The U.S. economy has experienced years of uninterrupted growth, but compared to most of the highly affluent nations on this list, wealth in the United States is distributed relatively unevenly. As a result, the nation has one of the highest poverty rates among wealthy countries.
