The world has ample data at hand to show more humane and at the same time much cheaper ways, even methods that will yield a profit. These ways have been abundantly illustrated by history and can be witnessed in operation every day.
England was repeatedly conquered and settled by brigands and misfits. When her people grew more homogeneous and orderly she sent her anti-social to New Zealand and to Virginia. In New Zealand with its opportunities these outcasts and their descendants prospered and were as orderly and conventional as the English society that banished them for England's good. The colonies in Virginia with access to land and a chance to make homes for themselves established a social order and formed communities more prosperous than the ones that sent them out. Many of their descendants are now successful and important members of every western state.
In fact, most of the European immigrants who have settled in the United States were the poor and the outcast, the misfits of European countries. With better opportunities and a chance to build up homes in a new land, their descendants are at least the equals of those who stayed behind. The growth and development of the United States westward from the Atlantic seaboard has been effected by the poorer and less intelligent, but often the more venturesome, who constantly turned West to get cheaper land and a better chance. The residents of these western states compare very favorably with those who still reside in the sections of the country which these pioneers left behind. It cannot be shown that the less intelligent have criminal natures. All that can be shown is that they have a poorer equipment to meet the stress and strain of life. To make most of this class safe, all that is needed is fairer conditions and an easier environment. If society could only recover from the obsession that what is necessary to regulate man is plenty of prisons and harder punishments, it would be fairly easy and infinitely cheaper to improve the environment from which crime springs than to visit vengeance on the victim.
The effect of education is very great. Many a subnormal and backward person has been educated so he could take a place in life that those with a much greater natural ability could not fill.
