Many factors influence your sleep and the quality of sleep. There is a relationship between your socioeconomic status and how well and often you sleep. For example if you are of a higher class you would generally not have as many problems of someone in a the low class that’s struggling to make ends meet everyday. When you have money, you can use that money on investments that produce more money for you, this way you don’t physically have to work and have and have more opportunities for consistent sleep than someone in the middle class that works overtime to try and reach the high class.
