I'd like to see a budget breakdown of what these companies spend on research, manufacturing, marketing, etc.

At a glance, from looking at CBO pages, it looks like average R&D spend is actually more like in the 18-20% range, and that this isn't unusual for industries, which makes sense since they have other costs beyond R&D.
