......Any other animal that refused to earn its keep would soon become extinct......

If you replace the concept of species with varieties of species then it can be said that natural selection is in the process under discussion. All are Homo sapiens, but there are varietal gene pools in competition. Rather than extinction, varietal decline is more likely.

The process is best observed in Europe. Liberalism promotes the equality of the declining variety because of misguided belief that even those who are a drag on society must be supported. The result will be that a stronger, more highly motivated variety will enter Europe and displace both the natives and the Arabs. They will come from Asia.

I disagree. Strength, motivation, success are irrelevant in that aspect. What matters is the number of children. You can have couple of degrees, tons of money, motivation but if you have less than two/plus children you are on your way to extinction.
