George Bernard Shaw's Prediction

In reviewing portions of "How Civilizations Die", I came across the following:

"The day is coming when great nations will find their numbers dwindling from census to census; when the  six-roomed villa will rise in price above the family mansion; when the visciously reckless poor and the stupidly pious rich will delay the extinction of the race only by degrading it; whilst the boldly prudent, the thriftily selfish and ambitious, the imaginative and poetic, the lovers of money and solid comfort, the worshippers of success, of art, and of love, will all oppose to the Force of Life the device of sterility."

Shaw wrote this in 1903.
