It is in Germany that the attempt to regulate prostitution still remains most persistent, with results that in Germany itself are regarded as unfortunate. Thus the German law inflicts a penalty on householders who permit illegitimate sexual intercourse in their houses. This is meant to strike the unlicensed prostitute, but it really encourages prostitution, for a decent youth and girl who decide to form a relationship which later may develop into marriage, and which is not illegal (for extra-marital sexual intercourse _per se_ is not in Germany, as it is by the antiquated laws of several American States, a punishable offense), are subjected to so much trouble and annoyance by the suspicious police that it is much easier for the girl to become a prostitute and put herself under the protection of the police. The law was largely directed against those who live on the profits of prostitution. But in practice it works out differently. The prostitute simply has to pay extravagantly high rents, so that her landlord really lives on the fruits of her trade, while she has to carry on her business with increased activity and on a larger scale in order to cover her heavy expenses (P. Hausmeister, "Zur Analyse der Prostitution," _Geschlecht und Gesellschaft_, vol. ii, 1907, p. 294). In Italy, opinion on this matter is much divided. The regulation of prostitution has been successively adopted, abandoned, and readopted. In Switzerland, the land of governmental experiments, various plans are tried in different cantons. In some there is no attempt to interfere with prostitution, except under special circumstances; in others all prostitution, and even fornication generally, is punishable; in Geneva only native prostitutes are permitted to practice; in Zurich, since 1897, prostitution is prohibited, but care is taken to put no difficulties in the path of free sexual relationships which are not for gain. With these different regulations, morals in Switzerland generally are said to be much on the same level as elsewhere (Moreau-Christophe, _Du Problème de la Misère_, vol. iii, p. 259). The same conclusion holds good of London. A disinterested observer, Félix Remo (_La Vie Galante en Angleterre_, 1888, p. 237), concluded that, notwithstanding its free trade in prostitution, its alcoholic excesses, its vices of all kinds, "London is one of the most moral capitals in Europe." The movement towards freedom in this matter has been evidenced in recent years by the abandonment of the system of regulation by Denmark in 1906.
