It is pretty insightful to see how a seasoned American Entrepreneur perceives Europe and the obstacles that can be found here. Not necessarily every obstacle applies everywhere. Some countries might even have different things hindering their competitiveness than those outlined by the article. But it definitely isn't all peachy for businesses over here (or there).
