Culture is a way of life for people of a race, nation or community.
It's has also been used to reflect upon one's (education) and their worldly knowledge and appreciation of "the finer things in life" such as art, music, poetry, dance, theater, literature, languages, travel, fashion, wines & fine dining. Some people call them snobs.
In the U.S. it is not as revered as it once was. Most people would rather associate with those they consider to be "down to earth". The kind of people who enjoy wearing a pair of jeans, a t-shirt, sipping on a beer and enjoying a BBQ dinner on the patio laughing with friends. The vast majority of people in the U.S. would rather be thought of as being "cool" than to be thought of as being "refined" or "cultured" even if they really do have a cultured background they downplay it.
