> Putting aside my dislike for considering horses as tools
Well, I labeled humans as tools as well, so I'm not treating horses any differently in that respect than I am people, so I think you inferred a slightly different connotation for tool than I meant. Interestingly, the ability to see horses as non-tools is possible largely because their usefulness as a tool was surpassed by other technology. The same with cats and dogs.
> You could say that the majority of humans are just seen as 'tools' to the people in power that are driven by profit.
Yes, that is one aspect of the current system. The main difference is that it's not the only aspect, as it was for significant periods of history for significant portions of the world.
> If you think this is far fetched, look at what's happening in places like Flint, Michigan. People were drinking poisoned water for decades, and those in charge knew about it.
This is only a counter-example if the problem comes out, everyone wants a change, and nothing happens, and then only somewhat, depending on how much people actually care. I'm not arguing that the world has magically eradicated corruption, negligence and shortsightedness, but I do believe that once exposed the public then gets to steer the response if they care enough. Special interests will still have a disproportionate amount of influence, but when the populace cares enough, that disproportionate influence is a drop in the bucket compared to the influence of an incited populace.
