The men-pick-up-the-check norm can also be modeled as an opportunity for men to signal in a costly way. An opportunity to signal may be positive or negative or neutral, depending on the game-theoretic details (as well as side effects further removed from the immediate “game”). Removing the opportunity from one group of people and giving it to another may well increase or decrease the aggregate social welfare and/or cause a transfer from one group to another.
ETA: In case it’s not clear, “working out or buying nice clothes” are not perfect signaling substitutes for paying for dinner at an expensive restaurant. Someone with good physique might have good genes, a lot of spare time, or just enjoys exercising. Nice cloths can be reused for other dates and hence can’t be used to signal interest in a particular person.
