Who wins in the end?
It could go either way. The ruthless will end up dead at the hands of another ruthless bastard until there is only one ruthless bastard left. And if the ruthless don't kill each other off in their quest for superiority, they'll probably die as a result of the toxic environment that will follow their long exercise of greed and neglect.
It could also be said that there is only one ruthless bastard and that the rest of the bastards are simple, subservient lackeys kissing the ass of the dominant ruthless bastard in the hopes that she/he will shove some crumbs off its table and into their waiting mouths, like baby birds squawking and screaming for their mother to drop a worm down their throat. In that sense, all but the dominant ruthless bastard are meek, and don't know it.
And even though it is said that the meek shall inherit the Earth, I'm sure that most of them are thinking, "Great. Just what I didn't want." After all, they'll have to clean the place up.
