That's just one more piece of evidence that Keynes didn't understand capitalism. That's pretty amusing, considering he actually was a capitalist. He just wasn't a free market capitalist.

He probably meant to say that about free market capitalism, and wasn't clear enough in his head about economic systems to differentiate between that and capitalism in the generic. In any case, capitalism is not the absurd belief that the worst of men, for the worst of reasons, will somehow work for the benefit of us all. Instead, it's the belief that wide-scale economic managers are no better than other people, and as such will overall do much worse for "the benefit of us all" than the emergent properties of natural economic processes -- and will have to violate individual rights in the attempt at economic management.

So why are you sharing this graphic with us?

Maybe it's because, regardless of what Keynes may have thought, it's still useful information for people interested in making money with their Perl skills.
