Natural resources are one way for countries to grow, but that's an extremely volatile thing to bet long-term economic growth on.
Australia is a prime example, at least for the moment. Cost advantage doesn't last forever either,

Twenty cities that host about a third of the country's population produce more than 60 percent of its patents. Inventors are heavily concentrated around top universities and research centers of companies like IBM.
Here's their chart breaking it down:
