Prostitution should not be legalized because it will expand the corrupt sex industry. Citing a study on the impact of legalization in Australia, Alice Leuchtag maintains: "Legalization in Australia has perpetuated and strengthened the culture of violence and exploitation inherent in prostitution. Under legalization, legal and illegal brothels have proliferated, and trafficking in women has accelerated to meet the increased demand" (qtd. in Gerdes par. 3). In other words, Leuchtag believes the legalization of prostitution has caused a rapid increase in prostitution, resulting in a high demand for prostitutes. The legalization of prostitution has caused the sex industry to expand to the point that the number of illegal brothels is greater than the number of legal ones. In fact, police in Australia estimate that there are 400 illegal brothels and only 100 legal ones (Poulin par. 11). This proves that the legalization of prostitution has caused the sex industry to expand swiftly and uncontrollably. Furthermore, research published by London Metropolitan University "confirms what several prior studies have shown, namely that the 'sex industries', sexual tourism, child prostitution and violence against prostituted people have increased markedly in all the countries that have liberalized their prostitution laws. . ." (qtd. in Poulin par. 14). In other words, the research published by London Metropolitan University shows that the sex industry has increased in all countries that have legalized prostitution. Prostitution would uncontrollably expand the sex industry, an industry that manipulates and takes advantage of women. However, adversaries believe that legalizing prostitution will control the industry. Opposition states that the legalization of prostitution would be beneficial because it would control the sex industry. According to the article “Prostitution” published in Opposing Viewpoints, “Citing data from European countries, advocates say that no evidence shows that legalizing prostitution encourages more of it or attracts sex tourism” (“Prostitution” par. 16). This means that prostitution would not increase because of the legalization of the industry. Furthermore, by legalizing prostitution and allowing the issues of prostitution to surface, the sex industry can be adequately controlled instead of ignored (Liberator par. 8). Prostitution will remain out of control as long as it's illegal. Because prostitution is illegal, copious amounts of prostitutes are forced to work in secret and in unhealthy working conditions (Liberator par. 8). Following legalization, prostituted women could be brought off of the streets and their work could be managed by the government instead of by themselves. While legalizing prostitution would give prostitutes the opportunity to get off the streets, the industry will still not be able to be adequately controlled. A significant amount of brothels currently operate illegally in countries where prostitution is legal, and prostitutes are still left working in unhealthy environments. These uncontrolled environments often allow crimes like child prostitution to flourish.
