Why until the 17th century there were so few Europeans on the lands of North America, but by the beginning of the 19th century the situation had changed dramatically?

Before the intensive development of capitalism (formerly a fan in England, starting with the era of “fencing” and the transition to grazing sheep), there were few people in Europe who were ready to go overseas in search of a better life. With the development of capitalism there were more and more “superfluous” people; they sought to settle in areas with a climate most similar to that of their European homeland.
