In order to have babies, you’ve got to have a hope in the future … If you don’t believe in God, if you have an existential view of life, if this life is all there is, then, as Peggy Lee sang "why don’t we break out the booze and have a ball?" Why do we go to all that trouble? It’s only those with strong religious faith who have children. That’s the truth.
Robertson goes on to say that Europe has lost its "central core of religious faith" and embraced the philosophy of existentialism and people have stopped having babies because they see no hope in the future. As such, Europe is becoming "statistically irrelevant" while the US, though its birthrate has declined as well, has made up for it by allowing a "wonderful flood of immigrants."
