You seem like the type of person that will take advantage of others when a loophole law permits it. Sure, it may be legal, but it still makes you a bad person in my book.
My point is that the niches exist to be exploited by the least scrupulous among us. As long as the niches exist, they will be exploited. Resenting that is akin to resenting the biggest fish in the pond for being so damn aggressive - it's pointless. We live in a pond, and we should focus on maintaining the nonviolent and often ecosystem-benefitting nature of the exploitation (since it is hard-won and precarious), rather than resent the inescapable reality of its existence.
