Bottom line:

if you are a copper miner, you won’t lose any sleep should the penny get…if you’ll excuse the expression, pinched out of existence.

The bottom line in a decision or situation is the most important factor that you have to consider.

1. You won’t lose any sleep should the penny get pinched out of existence. 假设、虚拟语气should=if
2. If you’ll excuse/pardon the expression （做插入语）由于pinch 听起来稍有不雅，所以说“请原谅我的用词”。
3. pinch pennies 抠门
4. 如果你是一个采铜矿的人，你不会因为便士被取消而失眠。
