Her : ........ Thus, you can have X in exchange of Y. Do we have a deal?
Him : no ma'am , that doesn't sound fair. I do not wish to walk in it.
Her : Life is not fair, get used to it.
Notice, that she's trying to force a deal on him, which he does not want, and she is justifying it as "life is unfair".
But certainly he does not need to accept additional unfairness.
Word search : how would you encompass the entire attempt of trying to force a deal and justify it using overall nature of life?
A single word is sought. If that is impossible, a phrase is okay too. Thank you.
My attempt : I considered gaslighting, but it is too broad in scope, and does not quite capture the sneaky attempt to hide behind life's unfairness.
So it should be noted that I am searching a word to highlight the sneaky attempt to hide behind something unavoidable ( like life's unfairness) and the force additional unfairness on people ( like the seller here trying to enforce her proposition to the buyer who finds it unfair. She thinks because the buyer accepts life in general, he must accept additional ballast like her too)
I hope I managed to explain what I am seeking. Thank you.
