It’s a Libertarian/Liberal ideology to believe that consent in transactions is discrete and that there’s no such thing as partial consent via coercion.

Liberal/Libertarians would argue that an unfair low wage employment is fine because the worker agreed to do it so they shouldn’t complain. They have often argued that people could sell themselves into slavery if they consented to it.

We know that it’s not that simple and that power, economic and social, is very important to any transaction and who benefits from it.

To a Liberal, every deal is a square deal - proved by the fact that all parties agreed to it. They cannot conceive of an oblong deal that benefits one party far more or even harms someone who is pressured into it
