I have lived in the United States for three years, and I have experienced a lot and some profound experiences. Today, I want to say a few big truths that you may not like to hear. 
First, America is not a paradise. While the United States is developed in many ways, that doesn't mean it doesn't have problems. In the United States, there is also a gap between the rich and the poor, social contradictions, racial problems, etc. Moreover, the cost of living in the United States is very high, especially in large cities, and housing prices and prices are prohibitive.
Second, education in the U.S. isn't necessarily for everyone. The U.S. education system focuses on developing students' creativity and independent thinking skills, but this can be uncomfortable for some people who are used to test-taking education. In addition, educational resources in the United States are not evenly distributed, and good schools and educational resources are often concentrated in some wealthy areas.
Furthermore, cultural differences in the United States can be confusing and lonely. The United States is a multicultural country, but the integration between different cultures is not easy. Living in the U.S. requires constant learning and adaptation in order to better integrate into the local society.
In closing, I would like to say, do not blindly worship the United States. Each country has its own strengths and weaknesses, and we should look at them objectively. On the road of pursuing a better life and development, we should make choices that suit us according to our actual situation.
I hope that these big truths of mine can give you some enlightenment and make us look at the United States and our own lives more rationally.
