[Defeat]

Philoophically speaking, they are in a situation in which they must make decisions according to their demands and opporunities which are present to them, therefore i dont they have complete freedom of choice. Plus being prone to diseases and other viruses, and for what? some money, because they need it to feed themselves, if they dont they lose their house, or the people which give them 'homes' so they work 'work-from-home'. They are pressured in most cases.
It can either be beneficial to them, psychologically they may be happier and with their work conditions.
Or the other, which is a 'forced' circumstance. But either way i dont believe they have complete freedom (as Sartre would say).

But this is interesting, ethically speaking, there are some principles of society which are conflicting to eachother, such as a way to generate an income or die of starvation, or helping a man/woman to feel 'happier' temporarily. But it does not look good in the eyes of society, no matter which angle you look at it, because it wont be accepted as a 'norm', they will always be treated as 'honour-less' .
If you want to add some points of perspective by a sex-worker, read this but i still wouldnt rely it on that much, since you must stick with the subject at hand -http://www.inquiriesjournal.com/articles/28/a-feminists-argument-on-how-sex-work-can-benefit-women

I need to first make the point that I am strictly talking about sex work and not sex trafficking. Taking the forced out of the picture may take out the extreme forms and keep it in context throughout the paper.
