My advice is not to judge others.
Just because a women is in a job that most of us would consider degrading and wrong, it does not mean she does not have the right to be a human being. Sex workers must be respected as human beings, too. Respect is something everyone deserves.
Prostitution is hated in our society and they are often neglected in the society. Poverty is the main reason for this. Lacking adequate food these poor women are also employed in prostitution as they have no other job if they are properly monitored, they can be prevented if there are adequate employment opportunities.
