Okay. Let's answer the question. Can we make a big difference? It's not a big difference. Can you make any difference as a mere individual facing the enormous power from a big company and even a government? Many people probably say no way. I cannot make a difference. I cannot fight against a big company. I cannot fight against the government. So, we are sometimes frightened or we're sometimes overwhelmed by big business or big government. And I have to say that, to a certain extent, that's true. And I also experienced my helplessness when I hadn't shared some issue with the big company. And at the time, I thought that I'm so helpless, I mean I could not make any difference. How can I fight? How can I voice up against this big company? Nobody would listen to me. I mean, the big company has all the money to use this media and advertising and so on and so forth. So, even if I have a good reason to believe that the company has done something wrong, but nobody will listen to what I say. So, I felt so helpless, and I almost gave up. Should I accept that as my fate, because I'm just a single mere individual, one individual, individual consumer? Let's look at this picture. Let's look at this photo. What can you see? Lots of cars moving in one direction. Lots of cars moving in the same direction, and lots of individual cars, individual cars moving the same direction. It's much like people, bunch of people walking toward the same direction. Now, what can you see? There is one individual crossing the road and then all these cars are stopped in front of the crosswalk. Why? Why? Because of this one car. Because of this one individual. All these cars following must stop as well. Right? And if this car were or if this individual is not aware of this human being. And therefore the car just stopped driving through that. Then there might be a big accident. But all these cars are stopped because of this single car. But actually, I experience this kind of situation every day. Why'd I drive? Why'd I drive? I always stop in front of this traffic sign. And when I look back, all these cars are stopped behind me. I mean there are big cars, more expensive cars, and trucks, and SUVs. But every car must stop because of me. And if I do not observe this traffic sign, then I go, then all the cars follow me and then there might be a big accident. Okay, you get the point right? You get the point. My example might not be a perfect one, but I think that it gives us some idea about what do I mean by an individual consumer, and why is it important for individual consumers to be aware? Why is it important for an individual human being, individual person, individual citizen in a country to be aware of and to be sensitive to the moral and ethical issues. So, the answer to this question, can I make the big difference? Can I make a difference? Yes. Sometimes an individual consumer is more powerful than anyone can imagine or any company tries to indicate. So, one single consumer is very important in power. And therefore you can make a difference. You can make a difference to your value chain and the ecosystem and society, your own country and the world and therefore, the entire human kind. But one condition is you got aware of this, you got alert, you are very active, you must be willing to make a conscientious choice. You have to make a choice that is consistent with your own conscience. Think about this Volkswagen case, why the company's responses were very different in Korea than in the US. Because in the US consumers were more aware of, more sensitive, and consumers were more willing to take an action. On the contrary, in Korea, consumers just ignore the big things, the important issues in society. They were so much consumed by their own inner gaze, individual gaze. And then in that kind of context, in that kind of environment, why should company apologize? Why should company behave? In a way, consistent with the sustainability. Okay, so, this is the sort of a philosopher and more a foundation of a supply team management. When I say that the supply team management in this course is about strategy, managerial, it's about people, it's about human beings. Without trust, nothing happens. Actually, that's one of those sayings done by Confucius. Confucius was preaching that without trust, human society can not function, human society can not sustain. And that's really, really important point for supply chain management. Without trust between supply chain participants, supply chain management does not function, supply chain management cannot sustain. And then the trust must be in the right direction. What do I mean by right direction? It must be morally and ethically right, in a sustainable manner. And who should be the steward that measure that kind of objection is sustained? Consumers. So, that's why I think it's very important for us to bring these consumers into this big picture of a supply chain management. And that's one point I want to make very clear in this particular lecture. And that's the one point I want to make through this extra introduction chapter, extra introduction lecture. So I hope, I'm not sure, but I hope. I hope after you study this course, you will be a better, more capable manager, the value of integrity. I'm not a professor in ethics, I'm not a professor in philosophy, I'm a professor in management. I'm a professor, business school. So you might wonder what on Earth a professor business school shouldn't care about acting and integrity and philosophy, current moral foundation. I think It's utterly relevant. It's very important for me to talk about those things, because without those things, supply chain management cannot function, cannot perform, and I hope that you will see that. You will see why I'm saying this. You will see what's the point of today's lecture. So, eventually I want you to enrich your supply chain, your value chain. And therefore you will achieve your own goals, whatever your goals. If you want to be a good manager. If you want to good CEO? I hope that this lecture will help you to achieve your goals. Okay, I think that I made my point very clear, right? And you understand why I needed to talk about these whole ethical issues and moral issues. Because these are not just philosophers interests. These topics are enormously important in making sure that the supply chain management create value. Create value in the right direction. At the right time, in the right place. So, I'm very pleased to see all the gain, and I hope that you enjoy my course. And again, I hope that this course can help you to grow, and also, I want to grow myself. I myself want to grow, by our journey. You enjoy my course and I also will appreciate any feedback and any good suggestions from you as well. So, good luck to all of you, especially good luck to your journey of learning. Learning this course, supply chain management, a learning perspective. Thank you.
