Explanation:

In a way, Crevecoeur wanted America to be a "perfected Britain". He liked some of the aspects and characteristics in Europe, but others he felt should be done away with. "As in Europe, of great lords who possess everything, and of a herd of people who have nothing." Crevecoeur disliked that in Europe, it seemed that those higher up in the economy controlled everything, leaving nothing for lower class groups. He sought change for America stating, "The rich and the poor are not so far removed from each other as they are in Europe". But there were also some qualities Crevecoeur hoped would be utilized by the colonists, such as the European's etiquette. He saw the "back settlers" of America as unrefined and barbaric, and hoped that others would not follow their example.
