Exploitation is the action of treating someone unfairly, according to what is morally right for personal gain.

When two adults CONSENT to a transaction, even if it’s prostitution, I suggest they, and they alone determine what is fair, and just to them. They probably don’t need us in the West dictating what their values ought to be.

If passport bros determine they prefer women in developing countries to those in the USA, then that’s their prerogative.
