Switzerland's confidence in the national government

Here is an interesting piece of info that I came across today. If you look at Public Governance as a matter of trust, guess which nation comes out on top? Not only is Switzerland No.1, from 2007 to 2014 confidence in our national government increased by 12%. Might that be because we live in a direct democracy? As the father of a very dear Swiss friend of mine once said: "You are lucky to live in a country which guarantees you a right to vote. Use it!"
