When employed in your job you sell yourselves into temporary slavery. You'll not feel like a slave only so long as you believe you can quit your job. In a society with rough economic equality, allowing you to quit your job, the exact amount of payment for work, so long as it is sufficient for a basically good life, you'll treat as a meaningless economic artifact, or the result of the gangsterism of criminal members of society who literally can be lived with. But the very second you know you can't quit you'll feel like a slave.
Prostitution is a special form of employment slavery that directs one human body into contact with another body.
People in a literal sense make their lives with each other by bringing their bodies close to each other. A society is composed of people who want to live near each other.* The life they make with each other is judged good or bad by how much they want to stay in each other's company.**
A home is made by the comfort people feel in each other's presence. You want to go home to your friends and family because that is where you feel good, which is a matter of the body, not of judgement. When your body is forced by economic conditions to be sold into slavery, the fundamental good of society and home can no longer be recognized because no longer can be acted upon: the body that should want to find or make a place in society cannot freely do either, and the home the body needs to find is confused by the false home that has been pretended to in prostitution.
Economic inequality both forces large numbers into prostitution and, by creating the acceptance of employment as slavery, makes prostitution seem acceptable as only another kind of employment, all of which is forced to one extent or another. However prostitution is not just another kind of employment. It is a kind of employment that by threatening the conditions of private life and of social development leads to destruction of all aspects of life not presently regulated by slavery. It is the economic actively at war with the personal and social.
