From the Daily Mail report:
Researchers also found that after Norway introduced a ban on buying sex, street prostitution fell between 45 and 60 per cent, with no evidence of it moving 'underground'.
By contrast, in Germany, selling and buying sex have been legal since 2002. But this hasn't caused trafficking to disappear – in fact quite the reverse. By 2007, the UN had recognised Germany as a top destination for victims of trafficking.
A 2012 study of 150 countries showed that decriminalising prostitution results in more prostitution – which means more trafficked women. Whenever something is legalised, the implication is that society condones it and so more people do it. And the need for reform is not just about trafficking.
Today, prostitution in Germany is an industry thought to be worth about £11 billion a year. Ten-storey 'mega-brothels' offer a queasy kaleidoscope of sexual 'services'. And the number of prostitutes has mushroomed – there are an estimated 400,000 women working in the German sex industry, attracting punters from all over the world.
When something is suspiciously cheap and plentiful, it's often thanks to miserable workers in cruel sweatshops. So it is with Germany's supposedly safe and decriminalised sex industry.
