Denmark Christian

so i heard this question from a Christian Doctor..?
what examples do you have of atheist countries that show that atheism can produce better outcomes of an economy?
well first i think he met countries that are less religious as seeing that the US is 95% christian..
well here:
Norway, Iceland, Australia, Canada, Sweden, Switzerland, Belgium, Japan, the Netherlands, Denmark, and the United Kingdom are among the least religious societies on earth. According to the United Nations’ Human Development Report (2005) they are also the healthiest, as indicated by life expectancy, adult literacy, per capita income, educational attainment, gender equality, homicide rate, and infant mortality.
You are forgettting one thing AMERICANS HAVE THE WORST DIET EVER!
