Question: My brain cells seem to be dying but this one is bothering me. What is the phrase that means something that you lose in process? Similar to occupational hazard? Or by product or side effect?

Example:

> 
> Poor people and animals are ———- of capitalism.
> 
> 
> 

So *poor people* and *animals* are the subject and *capitalism* is the process.

Answer: 
I would say the answer is in the question and that the best word is 'sacrifice' or 'sacrificial victim'.

> 
> Poor people and animals are **sacrificial victims** of capitalism.
> 
> 
> 

They are surrendered, in a sacrificial way :

> 
> Sacrifice : a. The destruction or surrender of something valued or desired for the sake of something having, or regarded as having, a higher or a more pressing claim;

Victim? or maybe casualty? Something that is badly affected by a situation.
