Because they are as useful for Society than other Women, Prostitutes want to be better treated and respected than they are. Therefore they can argue in new economy that they not only have a social play, limitating sexual criminality as usual and helping men to stand their condition of married men, but having a non negligible play in Economy as much now.
New Economy of those last fourty years, especially based on Services and not on Industry anymore does need Prostitution. As a French porn-movie maker said recently on French-TV, new 'hi-fi' technological goods were introduced and sold during those last decades thanks to pornography. And in fact the link between sex and technology is known by philosophers since Ancient Times. Regarding this, some Muslim or Banks are trying for example to avoid investments in Prostitution for their customers; but this is almost impossible and this kind of ethical investements (muslim people think it is 'ethical') are rather Utopian.
So why are Whores not as well considered now than they were in some Ancient Pagan civilizations? Some of them are indicting Christianity; but in Europa Christianity is reduced now obviously to a Folklore and does not have coercive force anymore. If the State and the Government was not helping Catholic Church as it is doing in France, there would probably be less than 3% of Catholics. No need to mention that for the same touristic reasons, old Churches have to be maintained in Italy or Spain too.
Therefore there is no praise of the marriage in the New Testimony. Jesus is constantly mistaking Jewish old Politics and its Social System; he was shocking Pharisian Jewish by breaking their laws; and History does prove that Politics is just Sand as Time. Nazism is based on Family and Political Utopia, not Christianity.

Explanation is that Liberalism (including nazism) is a merchant's religion of 'progress'. Last point of 'progress' is an idea coming from Christianity. If it was a regular Pagan Politics, Prostitution would not make any moral problem. But this is very difficult to make 'Prostitution' a 'progress', not just only because of feminists that do not want the body to be just a thing for sale. Stupid people only can think one can get rid of the 'Progress idea'. This is mainstream faith! And there is no Politics or States in History without a religious Cement.
