In social relations, individualism asserts its influence om many aspects such as morality, ethics, or financial matters. Also individualism reflects a continuous frontier between the individual and the cultural. For being self-reliance, Americans approve self-motivation,which in the sense of long-range goals, as well as for a specific and immediate task.展开更多
