I certainly wouldn't attempt to argue against that scenario. But as you point out, cows at least reward us with tangible benefits, and the rewards include not only milk, but meat as well, and abundant supplies of manure, for all the avid organic gardeners out there.
But when it comes to deceiving humans by means of their guile and their insidious, seemingly-subservient behavior, cows are just pikers, compared with dogs and cats. Dogs and cats have no peer when it comes to ingenuity and imaginativeness.
Consider this: Who among us would be brilliant enough to attempt to captivate and dominate the hearts and souls of the dominant species on a planet, by clawing, biting, and otherwise ripping their upholstered furniture and draperies, soiling their carpets, and defecating on their lawns and sidewalks? Would it ever occur to us that the way to win over their undying devotion is to pretend to be happy to see them, so that we have an excuse to jump up on them to wipe our muddy feet on their clothes?
Or would we ever think of slobbering all over their face after chewing on a road-killed skunk or some other dead varmint, in order to convince them that we are simply displaying our affection by means of wet kisses? I doubt that even the most innovative among our species would figure out that rolling around on that dead skunk, or snake, or whatever, in order to get our body thoroughly saturated with the pungent odor, and then regally posing on their bed, or couch, or their favorite easy chair, would be instrumental in winning a lifetime of luxurious living.
Would we ever be capable of figuring out that the key to ensure that they love us enough to provide us with free, delicious food, a nice soft, warm place to sleep, and all the expensive healthcare services we might ever need, from cradle to grave, is to mark their window panes and certain prominent parts of their furniture with our urine, every time they turn their back? And while they might have a hit or miss exercise program themselves, would it ever occur to us that all we have to do is to claw on the door, or bark at them, in order to persuade them to get up off their butt to turn us out to do our business, or to take us for a walk during a blizzard, or a rainstorm, so that we can play in the snow, or water, or mud?
Clearly, the answer to all these questions is an unequivocal, "No!" There is little question that our cunning pets are much smarter than we could ever hope to be. To add insult to injury, for the most part (outside of a little informal entertainment now and then), they provide us with no tangible benefits.

And as fast as animal rights are currently progressing, it won't be long before they will be granted the right to vote, and after that happens . . . Look out! After that point, they will no longer have to pretend to like us, because they will be able to easily outvote us. Life will never be the same again. And to think that a generation or so ago we were worried about being taken over by the Russians, and now we are concerned about being owned by the Chinese.

Clearly, we have been ignoring the elephant in the room.

P. S. I hope that this post doesn't offend anyone (or any pets that might be reading it). I've had pets all of my life, and I'm just reporting some of what I've learned from them.
