In Russian we have an idiom that translates to English literally as "to get more milk from your cow and spend less food, you should feed you your cow less and milk it more". It's usually used sarcastically. Are there any similar idioms in English?
UPD for @Amande: let me google that for you
UPD2 It's often used in job context when talking about poor management. In other words, I'd formulate this idiom as "Be as selfish and cruel as possible, even if it harms your own interests".
