对于需要担心钱不够用的美国人来说，我的建议很简单：买你买得起的东西，并且自己做饭。

To those Americans for whom money is a concern, my advice is simple: Buy what you can afford, and cook it yourself.

我明白了：只买你买得起的东西。

I learned: buy only what you can afford.

很明显收入是很重要的：收入决定了一个人可以买多少东西，因此决定了他们是否能够负担得起一些事物，比如能否吃饱，而收入衡量法的批评者们认为这些更重要。

Income clearly matters: it determines how much people can buy and therefore whether they can afford to do the things, like eat enough, that critics of income-based measures think are more important.
