Not every immigrant who comes to America fits the definition of a pioneer. Their intentions for coming are to obtain better education for the children, better job opportunities, better standard of living. All noble intentions. As any family, the newcomers will make many decisions. It is often easier to just continue doing what they used to do in their country or what they see the people around them doing.
Years go by.
The immigrant family plugs along, adapting here and there. The parents come to a realization that life in America is complicated and difficult, not easier than in their own country, in fact, in many ways harder. They are proud of some things, but regret others. They often feel lonely. They are not satisfied with their lives, but will rarely admit it.
