What influence do the conditions and experiences of early American immigrants have on people's lives now?

In the early immigration history of the United States, a large number of Puritans were persecuted in Britain, and Puritans, dissidents and poor people in other European countries were also persecuted. When the first settlers arrived in North America, they found that the environment was harsh and they were isolated from European civilization. In order to adapt to the new environment as soon as possible, they are more pragmatic. In order to develop this fertile virgin land, immigrants need to break away from convention and solve some practical problems. Under this historical background, pragmatic philosophy began to take shape in the United States. In the eyes of Americans, practicality and effectiveness are the truth, and success is the truth. American immigrant culture mainly emphasizes the pursuit of democracy and freedom, advocates open competition, pays attention to rationality and practicality, and especially emphasizes personal J value.
