That may be the case, but to conclude that a higher quality of life will inevitably lead to population decline is fallacious. Birth rates can and do fluctuate from a variety of circumstances. For instance, nowadays the countries with the highest GDP are likewise the most inundated with cultural influences through media and other sources that discourage procreation. If birth control and abortion weren't so widely utilized, birth rates in those countries would be off the charts from the sheer promiscuity alone.
Population growth and GDP per capita are inversely correlated in every country in the world, no exceptions.
