The prostitutes in Holland are probably more in power than most people here realise, the industry is controlled and the girls are all free to decide what they want to do. However the rise in eastern European criminal gangs active in the area has caused the goverment to close certain brothels in a clean up campaign. The Rose Buurt will not be closing and coffee shops will still be around, I personaly believe if your only reason for visiting Amsterdam is the coffee shops then you should stay where you are.
Amsterdam is so much more than just hookers and hash , the ignorant people that believe that's the only reason for going there is something the Nederlanders want to get rid of.
Ik hou van Nederland !
