Using cold, hard statistics from the past several years around the globe, Arthur Brooks reviles who is the most warm and fuzzy inside. From that the author states what policies the United States is doing that helps or hurts our GNH. The only problem with it is that it seems destined to become a political and not Sociology book due to his findings. Despite saying, for example, there are happy secular liberals (there is just fewer of them), it is getting bashed by the left while praised by the right. Both of which is a shame, since his true purpose is to show why certain people are happy, not necessarily how to make one happy, from an individual standpoint. He isn't saying conservatives are better politically. Just more likely to be happy.
The only time he does show how to make happiness is where he puts down what our leaders national agenda should be if we want higher GNH. He is looking at the macro level, not the micro. Topics explored include: political affiliation (conservative vs. liberal only; there is no data on libertarians or more specific affiliations yet), religion, family (does kids and marriage really bring happiness?), freedom and security (does the Patriot Act affect our GNH?), work, and money.
I wish there was more content for the price, which is why I'm only giving it 4 stars. Hopefully this might start some new studies to fill in the gaps.
