There are a lot of studies that measure not only the nation wide capacity to innovate, but all sorts of factors - political stability, business sophistications, etc.
For example check the GCI:

I'm not german, but I have lived around 8 years in Germany, I studied at a technical university there and worked at one of the Fraunhofer Institutes, which are mentioned in the article I have to say - they are definitely doing it right. I mean... just comparing how affordable universities are there. I am always amazed when I read stories about students in the US who graduate with $50.000 or more in debt. What I paid in Germany was around $300 per semester (for which I received also a travelling ticket for the entire transport system in the entire province... just the value of this ticket exceeds the $300) and that was about it. Later they introduced semester fees and I had to pay around 700$ per semester. And that was really high. I mean ... people were protesting and the province's government removed the fees.
And it's really easy to find a part-time job in your field of studies in a high-tech cluster. In the case of my university the government spent like 2.5$ billion to extend the existing high-tech cluster so it can acommodate another 10.000 highly skilled researchers.
This is all happeneing in a small city with 250k people. In areas like Stuttgart and Muenchen it's even crazier what they are doing.
The only thing I am not fond about Germany right now is the high taxes. But AFAIK the government are planning in reducing the tax burden on companies to keep the economy competative.
I don't know... is it easy to find a part time job in your field of studies in the US?
