结果，这个家庭总共支付了45,000美元的必需品，而他们的可支配收入只有25,000美元（70,000美元-45,000美元）。 通常，家庭或个人可以用可支配收入做两件事：储蓄或消费。 有时被称为“疯狂的钱”的可支配收入可以花在您可能想要的所有东西上，但除了“跟上琼斯”，实际上并不需要其他任何东西。 自由支配收入通常用于外出就餐，旅行，乘船，休闲车，投资以及成千上万种我们真正可以“没有的生活”。
澳大利亚Micro Economy代写：储蓄或消费
As a result, the family paid a total of $ 45,000 for necessities, and their disposable income was only $ 25,000 ($ 70,000-45,000). Generally, households or individuals can do two things with disposable income: savings or consumption. Disposable income, sometimes called “crazy money,” can be spent on everything you might want, but you really don’t need anything other than “following Jones.” Discretionary income is usually used for dining out, travelling, boating, recreational vehicles, investing, and thousands of kinds of life that we can really “don’t have.”
