I disagree with this statement that people are less satisfied than people were in the past just because the world is changing quickly than before. Because nowadays, our world is changing batter and batter, the quality of lives people have is also improved a lot. Even though people are stress about their work. However, they can have some different way to express themselves in this world. Our world is changing and developing more and more convenient for people and improved quality of lives a lot. when you ask someone lived 30 years ago, he can never imagine how amazing our world developed today. Now, people can use online shopping to buy different things they like even form a different country, they can easily get satisfied by those convenient twenty-first-century inventions. People today can travel to everywhere by using different transportation, which people cannot imagine many years ago. The massive comuntation today also provide many chance for people to communicate with eachother easily, and keep in touch all the time.
