My source says this actually:
Mystery. Look at Iceland. It uses the same standards as we do. But it also has a population under 300,000 that is 94 percent homogenous, a mixture of Norse and Celts. Similarly, Finland and Japan do not have the ethnic and cultural diversity of our 300 million citizens. Even factoring in education and income, Chinese-American mothers have lower rates, and African-Americans higher, than the U.S. average. Environment matters as well. Lower infant mortality tracks with fewer teen pregnancies, married as opposed to single mothers, less obesity and smoking, more education, and moms pregnant with babies that they are utterly intent on having. Yet, there are still biological factors that we don't understand that lead to spontaneous premature delivery. It's a mysterious happening when a seemingly healthy pregnant woman suddenly goes into labor and delivers at six or seven months or has to face the shock and sadness of being confined to bed, hoping to hold on for another week, another month.
It hardly seems to support your point.
Also you missed this:
the Organization for Economic Cooperation and Development, which collects the European numbers, warns of head-to-head comparisons by country.
Such a contentious area is hardly one to make statements like this about;
That's where the rubber hits the road....That's where right wing bullsht ends
