Genuine progress indicator
Most economists assess progress in people's welfare by comparing the gross domestic product over time—that is, by adding up the annual dollar value of all goods and services produced within a country over successive years. However, GDP was not intended to be used for such purpose. It is prone to productivism or consumerism, over-valuing production and consumption of goods, and not reflecting improvement in human well-being. It also does not distinguish between money spent for new production and money spent to repair negative outcomes from previous expenditure. For example, it would treat as equivalent one million dollars spent to build new homes and one million dollars spent in aid relief to those whose homes have been destroyed, despite these expenditures arguably not representing the same kind of progress. This is relevant for example when considering the true costs of development that destroys wetlands and hence exacerbate flood damages. Simon Kuznets, the inventor of the concept of GDP, noted in his first report to the US Congress in 1934:the welfare of a nation can scarcely be inferred from a measure of national income. If the GDP is up, why is America down? Distinctions must be kept in mind between quantity and quality of growth, between costs and returns, and between the short and long run. Goals for more growth should specify more growth of what and for what.
BRIC
South Korea is one of the world's most highly developed countries and including it with developing countries like the BRICs is not deemed correct. However, commentators such as William Pesek from Bloomberg argue that Korea is "Another 'BRIC' in Global Wall", suggesting that it stands out from the Next Eleven economies with its BRIC-like growth rate, despite its Human Development Index being higher than some of the world's most advanced economies, including France, UK, Austria, Denmark, Finland and Belgium. South Korean workers are the wealthiest among major Asian countries, with a higher income than Japan and the strongest growth rate in the OECD. More importantly, it has a significantly higher Growth Environment Score (Goldman Sachs' way of measuring the long-term sustainability of growth) than all of the BRICs or N-11s. According to the IMF, South Korea's GDP measured by purchasing power parity is already larger than Canada and Spain. In terms of GDP per capita (PPP), South Korea overtook Spain in 2010. According to Citibank, South Korea will continue by overtaking Germany, Britain, Australia and Sweden by 2020, surpassing Canada, Switzerland, Netherlands and Norway by 2030 and taking over the United States by 2040 to become the world's wealthiest major economy. While measuring the South Korean economy by nominal GDP is inaccurate as the South Korean won is artificially kept low to boost exports, IMF predicts South Korea's nominal GDP and GDP per capita will surpass Spain in 2015. Economists from other investment firms argue that even when measured by nominal GDP per capita, South Korea will achieve over $145,000 in 2040, surpassing the United States, suggesting that wealth is more important than size for bond investors, stating that Korea's credit rating will be rated AAA sooner than 2050.
