Recently, I was besieged by some post-80s and post-90s generation on Weibo because I called on China to develop high-density cities, small family houses and use public transportation. Everyone unanimously asked, "Professor, why do you want us to live in a small room when you live in a big room in the United States?" I couldn't help but answer back: "say what you want wherever you go. China is short of land resources. China is not Canada. Most people want to live in small houses in China. If you don't like it, go to Canada." In fact, what's worse, I haven't said: "why can I live in a big room, but you can only live in a small room? Because I'm a professor in the United States. You're young and haven't done anything. Why is it your turn to live in a big room?" Some netizens probably heard the voice outside my words and left a message saying, "you may be brilliant, but not everyone has your ability, but shouldn't they live with dignity?" I had to tell him: I am not brilliant at home or abroad, at least in terms of material. Pursuing material is not my purpose of life. However, China has so little land resources and so many people. If people with average ability have to live in big houses to have dignity, where can we find so much land? Our husband and wife, from China to the United States, all the way to famous schools, from Peking University, Fudan University to Yale. This is not only the luck that most people don't have, but also the result of their own struggle. In the eyes of many people, this is also quite "successful". But I didn't own a house or live in a big house before I was 48 years old. In fact, before I was 43 years old (that is, before my daughter was 5 years old), I belonged to the humble family. The last few years of study. A family of three huddled in a small attic in New York. The heat of summer melted the candles in the closet. Now it's like yesterday. We also don't feel that we have no dignity. I don't understand that we didn't feel wronged living in the United States when we were 40. Why can't young people today stand it? I remember the most comfortable period of life when I was a doctor was when my husband and wife studied in Japan with their newborn daughter, which was between 1999 and 2000. Like many Chinese students studying in Japan, we learned that the Japanese were so crowded when we arrived in Japan. We lived in an apartment of about 50 square meters at that time. Japanese guests were very surprised when they came: "how can you live in such a big house?" The building we live in is the dormitory for advanced students of the "Japan Research Center" jointly run by American universities. One of the reasons for the large house is that the location is very poor, just next to the homeless relief center. Even at one o'clock one night, a drunken homeless man knocked on my door. When you visit ordinary Japanese families, you can see that their homes are often much more crowded than many middle-class families in China. Today, Japan's per capita GDP is more than $45000, while China's is less than $5500. Look at Boston, one of the most advanced high-tech cities in the United States. The annual income of medium-sized households (including singles) is more than 55000 dollars, and the population is only 600000. The density is much smaller than that of big cities in China, and there are much more land resources. However, recently, Boston is building 30 square meters of small apartments. This is also for the young professional class. Its purpose is to control the rent at $1200-1600 per month, so that young people can have a foothold. Designers said that these fledgling professional classes, with limited economic capacity, when they are energetic, start businesses and socialize outside all day long, and go home just to sleep. What they need is not expensive big houses, but to reduce the cost of struggle. In fact, young people especially welcome this arrangement. If a young man who has just graduated from Ivy League said to my professor who is over 50 years old, "why do you live in more than 250 square meters, and we live in 30 square meters? Where is my dignity?" In American society. I'm afraid you'll think such a person is a little crazy. No matter how rich a society is, strive from the bottom. Fighting from the starting point of having nothing is still "kingcraft" Lost this spirit. Society loses the impetus for progress. This reminds me of the words of an American columnist: "all middle-aged successful people, if possible, are willing to exchange all their achievements and money for the poor and humble life back then." Youth is the happiness and beauty of life. If you lose the ability to feel this kind of thing, you lose your life. Of course, I don't want to overthrow a generation with the concept of post-80s and post-90s generation. In fact, there are many younger generations who support me on Weibo. It is precisely they who tell me that there are indeed too many people in their peers who think that everything should be given to them by their parents. In my opinion, domestic elders should boldly admonish younger students: child, it's not your turn. What do you want? Earn it yourself!
