Same end goal.

Just an FYI: the book also describes the fate of a colony world called Galt that gets genocided and consumed by a hyper-capitalist’s clone army. The logic is simple. He wants more clones, and the best source of more biomatter fit for making clones is human bodies. He’s also been told all his life that he’s a superior life form, so what use is anyone “lesser?” It doesn’t matter that the Galtists consider themselves “rugged individualists”, they are less thans and therefore useless beyond making his numbers go up.

The book and setting is not shy about criticizing capitalism’s commodification of human life and disregard for suffering. It’s the entire point of how Expendables are treated, lol.

I don’t doubt that a movie had less time to make some of the themes more obvious, but they’d have had to completely remove the concept for it not to be clear.
