Why don't American tramps escape to the mountains?

There are many kinds of vagrants in America. Most homeless female vagrants suffer from serious domestic violence. In order to avoid "little people", they will choose to escape. Most of these women are black, with a high fertility rate. These women have no skills and low education, so it is difficult for them to find their place in society. Moreover, the United States is a big immigrant country, and some foreign "illegal immigrants" can only hide in the streets of the United States and live on food in shelters because they have no identification. In the United States, the law allows homeless people to sleep on the streets. As long as he doesn't do anything that touches the law, no one can do anything about him. As long as they are willing to work hard, these homeless people will find ways to avoid falling into this situation. Even if you flee to the mountains, the United States can't accommodate so many homeless people and food is limited. More serious things will happen.
