Here is a bit more about myself. I believe there exists a fair amount of research areas, not just in economics but in the whole scientific community, which are not fundamentally important but only unnecessarily complicated and tricky. For instance, I do think that there are only two founders of the new classical macroeconomics, namely, Robert Lucas Jr. and Thomas J. Sargent, excluding Robert J. Barro. The real valuable research that could benefit humanity and therefore enhance our understanding of the universe and hence the world is the research which is fundamentally and intrinsically important rather than the research which is seemingly complicated but not valuable in disclosing the true laws of the universe and the world. It is so unfortunate to see that we have so many scholars nowadays that would rather pursue the seemingly complicated stuff than pursue the really valuable and fundamentally important research which could have a real significant impact on humanity. I want to end with a letter from Einstein to his daughter to express my attitude towards the academic research as well as my belief in humanity.
"When I proposed the theory of relativity, very few understood me, and what I will reveal now to transmit to mankind will also collide with the misunderstanding and prejudice in the world. I ask you to guard the letters as long as necessary, years, decades, until society is advanced enough to accept what I will explain below. There is an extremely powerful force that, so far, science has not found a formal explanation to. It is a force that includes and governs all others, and is even behind any phenomenon operating in the universe and has not yet been identified by us. This universal force is LOVE." ---From Albert Einstein to his daughter
