How can it be exploitation if they have fully freedom in choosing to forgo the deal?<p>&gt;As opposed to associations of that word to terribly abusive situations, because abuse is never OK.<p>Even if it was as bad as the association you are making, it is merely a choice.<p>&gt;Unless you want to call leaving them in their current situation a threat<p>Here is where most people&#x27;s moral systems break down.  If their current situation involves death, then any deal where you benefit is seen as exploitation unless they think the exchange is fair.  But doing absolutely nothing, offering nothing and taking nothing, is seen as a neutral choice.  But only to an extent.  If you turn away a starving child at your doorstep, the action is seen as abhorrent.  But if don&#x27;t donate money to help feed a starving child elsewhere, even though such an action is easier than helping the child at the doorstep, that is just normal.<p>There almost seems to be some moral corollary to the bystander effect.
