Culture and society

Americans have traditionally been characterized by a unifying political belief in an " American Creed " emphasizing consent of the governed, liberty, equality under the law, democracy, social equality, property rights, and a preference for limited government. Culturally, the country has been described as having the values of individualism and personal autonomy, as well as having a strong work ethic, competitiveness, and voluntary altruism towards others. According to a 2016 study by the Charities Aid Foundation, Americans donated 1.44% of total GDP to charity—the highest rate in the world by a large margin. The United States is home to a wide variety of ethnic groups, traditions, and values. It has acquired significant cultural and economic soft power.

Nearly all present Americans or their ancestors came from Europe, Africa, or Asia (the " Old World ") within the past five centuries. Mainstream American culture is a Western culture largely derived from the traditions of European immigrants with influences from many other sources, such as traditions brought by slaves from Africa. More recent immigration from Asia and especially Latin America has added to a cultural mix that has been described as a homogenizing melting pot, and a heterogeneous salad bowl, with immigrants contributing to, and often assimilating into, mainstream American culture. The American Dream, or the perception that Americans enjoy high social mobility, plays a key role in attracting immigrants. Whether this perception is accurate has been a topic of debate. While mainstream culture holds that the United States is a classless society, scholars identify significant differences between the country's social classes, affecting socialization, language, and values. Americans tend to greatly value socioeconomic achievement, but being ordinary or average is promoted by some as a noble condition as well.

The United States is considered to have the strongest protections of free speech of any country under the First Amendment, which protects flag desecration, hate speech, blasphemy, and lese-majesty as forms of protected expression. A 2016 Pew Research Center poll found that Americans were the most supportive of free expression of any polity measured. They are the "most supportive of freedom of the press and the right to use the Internet without government censorship." The U.S. is a socially progressive country with permissive attitudes surrounding human sexuality. LGBT rights in the United States are advanced by global standards.
