Some immigrants are highly educated, have high incomes, and a lot of wealth. The richest cities and counties in Virginia, for example, have large and diverse immigrant populations. If you think white = rich, you need to rethink that. Asian-Americans, notably Indians and Chinese, have higher household incomes than whites.
