After eating to a certain extent, if you eat it again, the rice will The utility is negative, that is, not only can't give him benefits, but burden. The same is true for the person who bought the car. When he bought the first car, he felt much more convenient and had a great psychological satisfaction. When he bought a second car, because he couldn't use two cars at the same time, the second car was not as effective as the first car. Of course, the second car can also serve as a backup, and it will increase his display capital. At this time, the total utility is increased, but the increase is not as large as when he bought the first car.
