snip...It has to do with the natural fact that in wealthy, industrialized society, children are a financial burden rather than an economic benefit
Priorities are reversed in favor of 'things' (materialism) rather than in continuity of life. This evidences a lack of proper moral judgement due to loss of moral principles due to loss of.........religion.
We've seen the same effect in nearly atheistic societies such as Japan, moderately religious societies such as South Korea and Spain and highly religious societies such as the US and North African Muslim countries.
It has nothing to do with religion. It has to do with shifting economic realities. Few people can afford to have large numbers of kids in industrialized societies because the little goobers are so expensive to raise these days.
