It may be that a workman, i.e. a person who can only provide for his own needs and those of his family by selling his labor, can find no work, and for that reason falls into theft; but the author is of the opinion that in our days this almost never happens (leaving aside periods of crisis), and that if it happens the worker will generally find some one ready to help him, and that crime is therefore not a necessity. There is, indeed, absolute poverty, but it is almost always the result of a lack of courage and energy, and not due to a lack of work. It is not hunger, but a desire to procure the same pleasures as those enjoyed by the favored of fortune, that impels the working-man to commit crime. But this is not only the case with the working class but with other classes as well. For this desire belongs to every man; the millionaire envies the multimillionaire, etc. In order that this desire should lead to crime, it is not necessary that there should be a particular economic situation, but only a particular psychic condition—the individual must have his sense of honesty weakened or wanting. Desire will cease to lead to crime only when there is no longer any advantage to be gained by it, and since this is inconceivable, crime will always exist. This explains why the number of crimes committed by the proletariat is very great, but at the same time why the cases of forgery, bankruptcy, etc. are very numerous among the other classes. In 1880 the figure for crimes against property (and analogous crimes) committed in Italy by proletarians, compared with those committed by property-owners, was as 88 to 12, while the ratio of the number of proletarians to that of property-owners was as 90 to 10. These proportions are nearly the same, which proves that as regards these crimes the proletarian class is no more criminal than the others.
