These quality of life studies can be misleading. I love Europe but I know that there are problems - high cost of real estate for the most part, an educational system that can be excellent but is elitist with relatively few university graduates, a tendency to discriminate against immigrants. I don't think most Swiss own their homes - they rent. If you love art, history and urban life Europe is great but it's harder to make a living in Europe compared to the US. As for obese people, the problem is people's attitudes. You can get all the best organic natural food you want at low prices but you can also get junk food. What you eat is up to you but unlike Argentina you can eat well and nutritiously without spending a fortune. In Argentina you have to search all over the place for what is common in the US, you pay more in Argentina too. This is not Argentina bashing, just a statement of facts.
