deep pocket

deep pocket
从字面意思来看，“Deep pocket”是“深口袋”的意思，但其实“pocket”这个词本身就有“钱财”的意思：
pocket [ˈpɒkɪt]
n. 衣袋，口袋；钱财，财力v. 把……放入口袋；把……装进腰包，将……据为己有；赚取，获得（钱财）adj. 袖珍的，袋装的
所以 Deep pocket 用作名词，就表示的是“财力雄厚”，即“十分有钱”的“土豪”。

例句：

He spends money like water because he thinks his father has a deep pocket.

乔治很浪费，花钱如流水，因为他认为他父亲财力雄厚。

C先生面临经济困难，没有一位可靠有钱的人帮助。

pour money down the drain

pour money down the drain
这个就比较容易理解了，Pour money down the drain=把钱倒进排水沟，这意义显然就是表示“挥霍钱财”。

例句：

Unfortunately, all their employers could see in the safety concern was the threat of money going down the drain.

不幸的是，他们的老板只能看到大笔资金可能付诸流水，却对安全问题视而不见。

Does this mean that pursuing a management degree at this time is money down the drain?

这是否意味着，现在攻读管理学位就如同拿钱打水漂呢？
