What it simply says is the more money a company has the more money it has for R&D. Obviously! A company that has $1bn in cash is in all probability not going to have the same R&D budget if all of a sudden it has only $50m in cash.
I am shocked to hear that Nokia's profits dropped from $9bn to $300m in just two years. That is the most shocking profit drop I have ever heard and probably one of the greatest drops in history for any company.
