From what I've heard, those regressions aren't totally valid. It can simply be that poor countries grow faster (leapfrogging on the research of rich countries), but don't fund a lot of public R&D.

Once the regression hits a dead end (as it doesn't distinguish the causal factors), we jump straight to anecdotes - the Industrial Revolution, and the USA. Both of these are probably outliers.
