Yet another is the increase of single mothers living on welfare, up in the United States from 2.5 per cent of all the female population in 1960 to 10 per cent in 1990. All these rises are due partly to an increase in th numbers of those with a genetically based impoverished moral character, although this is not to say that other factors, such as the increasingly generous welfare support, have not also played a part. The genetic deterioration of western nations poses serious problems. The increase in the numbers of those with genetic disorders who can be successfully treated raises the cost of medical provision. The decline of intelligence will produce a deterioration in the quality of our civilisation.
Intelligence is a major determinant of the effectiveness with which jobs are performed.
As intelligence declines there will be fewer people with high IQs to maintain standards in the arts and sciences, the professions and business, and fewer with good average IQs to carry out routine skilled jobs such as those of the plumber and the electrician. At the same time, there will be increasing numbers of those whose intelligence is too low for useful employment. No less serious is the problem of deteriorating moral character. It will bring about an increasingly immoral society. Crime will continue to grow.
