Generalizations based on the minority is odd thinking.
I've based my comment on pure mathematics. China has a strict population rule in effect. One child per family. While not 100% effective, studies have indicated that China's strong economic growth is directly related to adherence to this, which otherwise would have remained economically stagnant, the economic gains
nullified by the increase in population without one child rule.
The Muslim/Arab World see birth control as a sin, their child per family ratio much higher than the industrialized nations, a duty to have as many children in the name of Allah. Minority today, yes, but at the present rate one day not in the too-far future may very well intersect with largest of Earth's ethnic blocs.
