Yeah that is the gist of Steyn's book. He also looks at Japan, China, and Russia. Japan is like Spain and Greece, they just aren't having kids. China has way to many men and too few women, so they too will experience a decline in population. And well Russia is just plain sad. The men are dying very young by our standards in the West and the abortion rate is through the roof. They have little hope for a better future.

It is weird, but in the life times of most people on this board we could see multiple cultures just disappear.
