A capital-labor split of Cobb-Douglas function is adapted for use in the context of economic growth. A capital/income ratio and two fundamental law of capitalism originated by Thomas Piketty illustrate capital inequality undervalued than labor inequality. In addition, the article includes export and external debt as strong alternatives. Empirical data of the World Bank are analyzed to demonstrate broad differences in economic sizes.
