Simplify the following text for a Grade 11 native English-speaking person.
Original: Another , however , believes that legalizing and regulating prostitution does not improve the situation , but instead makes it worse , creating a parallel illegal prostitution industry , and failing to dissociate the legal part of the sex trade from crime .
Simplified: Other people see a different problem : Legalizing prostitution would lead to some legal prostitution , that would well-regulated , and probably worked well . On the other hand , there would also be the illegal prostitution , which would not change much .
