Crevecoeur talks about America as leading the way for the rest of the world, and being more open for opportunities. This is directly said, "Here he beholds fair cities, substantial villages, extensive fields, and immense country filled with decent houses, good roads, orchards, meadows, and bridges, where a hundred years ago, all was wild, woody, and uncultivated!" (pg 40) This shows America as not just being a vast expanse of land ready for use, but as quick in development and leading the way in development.
This may be because "Americans are the western pilgrims, who are carrying along with them that great mass of arts, sciences, vigour, and industry, which began long since in the east" (pg 44) Crevecoeur here talks about how Americans use the knowledge and technology created in the east, and adapt and build on it to be the front runner in advances.
One way this is still shown today is the recent news talking about how passengers will be able to use gadgets for the entire flight on US flights. (http://www.bbc.co.uk/news/technology-24761329) This shows America as embracing the 'technological revolution', which many of their brands such as Apple and Microsoft helped to create and make the movement thrive. The video on the website dismisses the traditional means of entertainment on flights such as books and newspapers, almost suggesting they are out-dated and impractical, despite still being used by many, and that the new modern gadgets such as e-readers and tablets are the way forward. For US airlines to implement this idea, it shows the US as leading the way, quite literally, around the world that they are ahead technologically, with new and fresh ideas making daily life easier, hinting at what Crevecoeur was discussing with the US being ahead and leading the way, with all the knowledge carried over from the east.
