If it weren’t a whale; what if it were a man? If you kept a man in a cage, even a big comfortable cage, and told him to do tricks for you, and if he didn’t do the tricks he would go back into his cage without any food, he’d probably do the tricks; and if you asked him if he was happy to do tricks for his food, he would thank you for the privilege, and bow to you, and speak highly of you, and curse you ’til the day he dies.
How could he do otherwise? You will have taken the world from him.
There is nothing further to say on this subject.
There is, however, plenty to say on the subject of modern slavery, but more on this elsewhere, soon.
