Benjamin Franklin begins "To Those Who Would Remove to America" by warning that many of the popular ideas about America held in Europe at the time were false. For instance, he points out that even if your family is famous in Europe, you can't expect to be treated as famous in America.
In "Letters From an American Farmer," de Crevecoeur similarly notes that who your ancestors were in Europe doesn't define your identity as an American. Rather, the American identity is different and unique:
What then is the American, this new man? He is either a European or a descendant of a European; hence that strange mixture of blood, which you will find in no other country. I could point out to you a family whose grandfather was an Englishman, whose wife was Dutch, whose son married a French woman, and whose present four sons have now four wives of different nations. He is an American who, leaving behind him all his ancient prejudices and manners, receives new ones from the new mode of life he has embraced, the new government he obeys, the new rank he holds.
Both Franklin and de Crevecoeur thus point out that America is not "Europe-lite"; America is its own place, and Americans see themselves as Americans, not transplanted Europeans.
However, says Franklin, because land is relatively cheap and the population is growing rapidly, both farmers and tradespeople like carpenters and tinsmiths can easily make a good living in the United States.
In particular, Franklin recommends America for Europeans who want their children to find a good trade and make a good living, saying "they may be taught & practice profitable mechanic Arts without incurring Disgrace on that Account; but on the contrary acquiring Respect by such Abilities."
Similarly, de Crevecoeur notes that the American identity is based on one's ability to solve problems and make a living without help from wealthy ancestors or social status. As a result, Americans are more likely to do their own bargaining, take each other to court, and read newspapers carefully in order to be fully engaged in civic life. "As farmers they will be careful and anxious to get as much as they can, because what they get is their own," says de Crevecoeur.
By contrast, both authors note, life in Europe is settled in the same patterns it has occupied for centuries. Being born into a particular social class practically guaranteed you'd stay in that social class your entire life, no matter how hard you worked or how much money you acquired. A stable population also meant that new jobs weren't opening up, which made it hard to find apprenticeships. Meanwhile, land ownership had been settled for centuries; there simply weren't new farms available.
In America, however, a growing population meant growing demand for a wide range of jobs, and vast tracts of unclaimed land meant farms were cheap. People who wanted to work hard could establish themselves and change the fortunes of future generations, both Franklin and de Crevecoeur argue.
