I would rather have the chance of making it big (or fail) than have the government take most of it away with huge taxes and strict rules that make it really difficult to have a successful business.
"It includes things like life expectancy and education."
Life expectancy is low because of the vast amount of people that eat crappy food (and don't exercise) in the US. I don't think this is going to change any time soon (unless it's mandated by the government).
"Income inequality (Gini coefficient)"
This to me just means that in those other countries, the government is re-distributing wealth. People aren't earning more wealth. The government is taking wealth away from people by force and giving it to the rest.
The only thing I do agree with is our bad education system system. However, our higher education institutions are some of the best in the world.
I also wonder sometimes if the reason our "satisfaction of life" index is low is because of liberal democrats that want us to be more like Sweden, Denmark, and Finland.
Would you rather be happier or have less freedoms?
I also find it really funny because Sweden, Denmark, and Finland are not only very homogeneous, but very racist. It's very difficult to go against what is considered "normal" (IE: groupthink).
