Earlier this month, France made a major move: The country has now made paying for sex illegal.

If someone is caught paying for sex, they’ll be fined up to $1.7K for a first offense, and up to $4.2K+ for a second time. The offender may also be required to attend classes on sex workers’ conditions.

France isn’t the only country to pass a measure of this kind, or even the first: The country follows in the footsteps of the U.K., Sweden, Iceland, and Norway.

Advocates of the new ban claim that this will help sex workers get out of the trade. But sex workers are opposing this new measure, reasoning that it will expose them to more violence.

It’s estimated that France has between 20K to 40K sex workers. (Naturally, it’s difficult to get an accurate count.)
