The other day I heard this phrase as if it were the first time I’ve ever heard it : “we (or they) made a killing.”  This short sentence, more than most shows how the script of capitalism has evolved to the point where we use metaphors and images reserved for the brutal act of murder.  Competitive capitalism deems winning as a kind of killing. Losers die, they are killed. 

There is also the phrase "filthy rich".

This is a weird world we are living in!
