Although adding the required current production (which must be reduced) to the card explicitly like that is redundant (given that the rules state that the reduction is compulsory and must be done) it does simplify things for the player. This seems good.
It could be about the same with red-bordered production reduction. (Recall: red border = anybody's ... no red border = active player.) The icon at the top would also have the red border, and the text would specify that "someone" must have production rather than "you."
