@Setanta,
The Europeans when entering the boat to America did not leave their culture behind.
You European Americans still eat ethnical food from Europe and from other parts of the world and developed your own
You have music your own plus from Europe and other parts of the world
You have fantastic authors - the tradition to write books came with the immigrants
Artists came from outside and you have many artists
If you say America has no culture it sounds as if anybody moving to USA left everything behind of his/hers cultural heritage.
So if USA has no culture it would be because of the Europeans who forgot all about it.
And why has then Australia or Canada or New Zeland culture These countries are also shaped by Europeans.
