Prostitution is slavery, a last resort career to support addictions or pay off debt. You would get a real job and not be exploited if you have choice.
Not necessarily true at all. The two sex workers I know are intelligent, independent women without addictions or debt. They could work in many other jobs if they wanted to.
Exploitation implies an abusive imbalance of power, but there's no such imbalance when they do it of their own free will and could quit any time they want. And it's certainly not slavery when they can make more money in a night than I do in a week. Sex work is a "real job". You are providing a service in exchange for money, just like a plumber or a video game developer.
Are some women forced into prostitution and exploited? Yes, which is why its better for it to be legal and regulated. But not every sex worker is a helpless victim.
