I don't get this complaint? The leverage for R&D is vastly higher now than ever before: You leave Zuckerberg in his dorm room and you get Facebook. You leave Larry and Sergey in a garage and you get Google. You leave Steve Jobs and Jony Ives together and you get dozens of products in Apple.

The money in vs money out in research has never been more absurdly positive in human history.

This is why companies aren't investing in R&D, because they don't need to do as much as they used to, because a little goes a lot farther.
