Many Americans here seem to think that legalizing prostitution will change the dating game significantly and somehow give power back to men.

Prostitution is legal is many European countries like Germany, the Netherlands, Greece. These countries are still pretty feminist, there are still men who are ultra simps. Greece is an exception as it is more patriarchal , but it's mostly because of religion not because they have legalized prostitution.

Most men don't see visiting a prostitute as equally validating as having a woman truly attracted to you. Simps will always exist, legal prostitution or not.
