The Democracy Index by the Economist’s Intelligence Unit examines the state of democracy in 167 countries: electoral process and pluralism, civil liberties, functioning of government, political participation and political culture.
The ideal seems to emphasize democracy and human rights with a level of individual economic security.
The Democracy Index rates Australia as the 10th and the Netherlands as the 12th most democratic of the 19 full democracies.
It rates the U.S. as tied with Italy for 21st place overall, the second most democratic of the 57 flawed democracies. Brazil is in 51st place overall.
Thailand is 100th overall, in the middle of the hybrid systems. China is 146th overall, in the middle of the authoritarian systems.
What do 18 of the 20 countries ranked higher than the U.S. have in common that is different from the U.S.?
All of the eighteen — Norway, Iceland, Sweden, New Zealand, Denmark, Canada, Ireland, Switzerland (with a unique twist), Finland, Australia, Luxembourg, Netherlands, Germany, Austria, Malta, the United Kingdom, Spain, and Mauritius — as you can see on the index, are parliamentary democracies. And by all of our other measures, these are wealthy, prosperous, modern countries.
The U.S. has a presidential system.
The main idea of a presidential system is that the people elect a legislature, but they also elect a head of state who is also the head of government, aka, the president. Often the legislature passes laws, including budgets, and the president administers them.
The main idea of a parliamentary system is that the people elect a legislature, and the leader of the largest party becomes prime minister. The budget is administered by ministers accountable to the prime minister.
