This is a free-rider game. One party bears the corresponding cost, and both parties share the resulting benefits. Whether individual rationality and collective rationality conflict depends on the game’s rules. When A < 10, the collective should participate (or contribute). However, due to unequal income distribution, individuals are reluctant to contribute. To resolve this conflict, we should not deny individual interests (let the big pig press the button selflessly), but rather change the game’s rules (if the small pig doesn’t press, it eats a little less). Therefore, while free-riding, don’t forget to give something back to the other party. The willingness of the wealthy to be benevolent cannot exist without the approval (or “likes”) of the poor.
