Thank you. > The National Science Foundation estimates that U.S. R&D funding reached an all-time high of $499 billion in 2015. Of that total, the federally sponsored share fell to a record-low 23 percent while the business sector’s share rose to a record-high 69 percent. This jives more with what I've personally experienced. Also looking at the data in the paper mentioned in the OP I see a ~5% growth in corporate research spending annually since 1953. So I don't think the data supports the OP's narrative.
