The best is eventually the cheapest翻译剖析（一分钱一分货）

人性的弱点里的一段话，part3chapter2:

Afewdayslater,afrienddroppedinandlookedatthedraperies.

thebestiseventuallythecheapest不应该翻译成“最好的终究是最实惠的”吗？

但我看了五六本书的翻译，都是一分价钱一分货，好货不实惠之类的，为何？

The best is eventually the cheapest.

字面意思是：最好的最后是最实惠的。

实质意思是：买最好的，最后会用得久，自然也就是最便的了。

其实也就是：一分价钱一分货；好货不实惠。
