If you want an answer to this question, please read the story of Japan and South Korea's socioeconomic progress and policies adopted by them. These two East Asian tigers are classic examples for rapid socioeconomic progress in a short period of time. Though, policies are very important to such progress, but along with good policies, good governance and corruption free system also plays important role.

Steven, I like your idea and appreciate the relevance of your idea to fields other than education! However, I referred to the fact that global economies are witnessing a common trend=income inequality leads to disinvestment in social capital, thereby making some people more vulnerable to health problems, morbidity, and early mortality. How do we counter these problems by augmenting social capital in a short duration?

It is impossible to increase social capital (resolve income inequality) in the short term. Yet, income inequality does not necessarily lead to health problems, morbidity, and early mortality of the people. Nowadays the most deadly health conditions are almost all related to superfluous wealth, like the cardiovascular diseases, diabetes, and other metabolic syndromes, and it is feasible to promote good health in months by reducing consumption, just as what Luigi Cornaro had shown to us with his life-long practice:
