This has meant that the staff cost for cafes has constantly crept up and up and up and up and up.

这意味着咖啡馆的员工成本一直在不断上升。

Of course, this was not always  the case as employers could pay women less, which helped keep staff costs down.

当然，情况并非总是如此，因为雇主可以向女性支付更少的工资，这有助于降低员工成本。

In some places, let's say Shanghai, you might have a very high rent and a much lower staff cost, but by and large, around the world, the net profit remains the same.

在一些地方，比如上海，咖啡店租金可能非常高，但员工成本会很低，总的来说，在世界范围内，净利润保持不变。
