Phil Zuckerman has written a couple books that go over the statistical data showing that godless societies tend to do very very well;
“Based on a careful assessment of the most recent survey data available, we find that somewhere between 500,000,000 and 750,000,000 humans currently do not believe in God. Such figures render any suggestion that theism is innate or neurologically based untenable… High levels of organic atheism are strongly correlated with high levels of societal health, such as low homicide rates, low poverty rates, low infant mortality rates, and low illiteracy rates, as well as high levels of educational attainment, per capita income, and gender equality. Most nations characterized by high degrees of individual and societal security have the highest rates of organic atheism, and conversely, nations characterized by low degrees of individual and societal security have the lowest rates of organic atheism.” — Phil Zuckerman
In his latest, he even investigated the country and interviewed the people of Denmark to see what makes them stand out as a highly successful society.Society without God: What the Least Religious Nations Can Tell Us About Contentmenthttp://www.amazon.com/Society-without-God-Religious-Contentment/dp/0814797148/ref=sr_1_1?ie=UTF8&s=books&qid=1225283258&sr=1-1
