I think some of the most successful developed nations out there, like Germany or Japan, are hardly "nations of entrepreneurs". Instead, they are nations of highly skilled individuals where entrepreneurs play their role to bring them together.

 On the other hand, you can say that a lot of least developed nations on Earth are truly "nations of entrepreneurs", where everyone is a small farmer, or small retailer, or small something else - with little to show for it in terms of skill or innovation.
