First off Argentina is a Hispanic City and The US is an American state. There is a lot of diversity in the US while there is no diversity in Argentina. Argentina's flag is different from the US flag. Modern Argentine culture has been largely influenced by Italian, Spanish and other European immigration, although there are lesser elements of Amerindian and African influences, particularly in the fields of music and art. The country is widely known for the tango, elegant architecture, steak, wine, and soccer, while some of the most legendary figures of the twentieth century came from Argentina, including Eva Perón, Che Guevara, and Diego Armando Maradona.U.S. culture has also been shaped by the cultures of Native Americans, Latin Americans, Africans and Asians. The United States is sometimes described as a "melting pot" in which different cultures have contributed their own distinct "flavors" to American culture.Values
Independence. Americans strongly believe in the concept of individualism.
Equality. The American Declaration of Independence states that “all are created equal,” and this belief is deeply embedded in their cultural values
Informality
Directness.
That is all I know about the differences and similarities!
I hope this helped you.
