Views on American history and culture

History is a step-by-step evolutionary history, constantly expanding, and then problems appear, and then problems are not properly solved. America was founded by a group of European explorers and criminals. They are ambitious, capable and sometimes United. When they set foot on the American continent, regardless of your status in Europe, everyone should unite and fight for the same rights. This is a group of people who long for freedom. With the slave trade in Europe, the social structure of the United States began to change, and blacks, Indians and whites led to some serious social contradictions in the United States. As Obama became president, this problem was slowly solved. The history of the United States is a process of constantly adding spices, just like a tree constantly absorbing nutrients from the outside and growing. When he absorbs some dangerous ingredients, there will be a crisis, and the foundation of this tree is really solid, which leads to its ability to resist risks.
