De Crevecoeur

One important concept which De Crevecoeur discusses is the fact that an American is
'Neither an European, nor the descendent of an European...' He states that an American leaves behind his 'Antient prejudices and manners, receives new ones from the new mode of life he has embraced, the new government he obeys, and the new rank he holds.'
 This was evident during the 18th century as there was a 'Mixture of English, Scotch, Irish, French, Dutch, Germans and Swedes.'
However in this day of age it is evident that the vision of America can be considered as flourishing even more than before.
For example, the picture above shows Obama's diverse coalition of supporters in the new, emerging America. It states under the photograph that 'Blacks and Hispanics and other minority voters can no longer be ignored.' Therefore this shows that America has progressed since De Crevecouer's time.
As during his time, slavery was a dominant feature in their way of life. He states 'They are branded like cattle, and then driven to toil, to starve, and to languish, for a few years, on the different plantations of these citizens. And for whom must they work? For persons they know not, and who have no other power over them than that of violence.'
However, now they are no longer dehumanised but treated as equal. This is evident through the source which portrays the image of a diverse nation coming together in celebration of the first black president. Thus, now there is a sense of 'national pride' which De Crevecoeur discusses, yet now it it has brought more nationalities together.
