Wesley's grandfather was a sharecropper, farming someone else's land. wesley's father was a farmer who farmed his own land. wesley owns an international dairy company that is responsible for providing milk products to people all around the world. this reflects:

This reflects upward mobility and globalization. It also reflects a tendency by Wesley and his father to follow in their fathers' footsteps and choose a similar (in this case agricultural) career path. It reflects upward mobility because farming your own land is more prestigious and profitable that being a sharecropper, comparing Wesley's father to his grandfather's situation; and owning and international dairy company is more prestigious and profitable than owning one farm. Wesley's role in the world market also represents globalization, as this global market was likely not open to his father or grandfather.
