Are you saying that because both parties benefit then neither party can be to blame? Confirming, not sure based on your wording. If so, that assumes that both parties are going into the trade negotiations on equal footing. I don't think I'm the only one who would argue that's not the case in a great many rentseeker:rentee or owner:employee relationships. Even discarding any social or economic pressures in the current climate, the power of the rentseeker and owner allows them to shape the environment into one that benefits them more (see: lobbying and politics in the USA).
