| − | The competitions between huge numbers of self-interested individuals will lead to many possible income distributions. Among all possible income distributions, exponential income distribution will occur with the highest probability. Following the natural selection process "survival of the likeliest", the exponential income distribution is most likely to evolve and survive, and hence is called the "Spontaneous Order" by Tao.[3] By analyzing datasets of household income from 66 countries and Hong Kong SAR, ranging from Europe to Latin America, North America and Asia, Tao et al found that, for all of these countries, the income distribution for the great majority of populations (low and middle income classes) follows an exponential income distribution.[25]
