Growth is not an automatic birthright for an economy. For an economy to grow, it has to create the right conditions for growth.
Growth depends to a significant extent on the resources a country has.
The better the quantity and the quality of the resources the more potential it has to grow. However, natural resources on their own are not enough. There also have to be the skilled people to exploit the opportunities. Capital - more capital generally means more production, and more production means more growth. To get capital, countries have to invest and so the level of investment may be a big determinant of future growth.
