What is a community

Communities with in communities is what I think we have in this day and age. We have the well off in one sector and the middle class in another and the less fortunate in another. we have always had this class divide. Maybe for centuries probably since we started to barter for goods. yet separation from each other has become a thing we discuss and have been doing for years. what is the difference between a poor man or woman to someone that has everything. if you think about it nothing because we all breathe the same air. We all sweat and most work hard. the question is can we keep up with the Jones? why should we? Individualism is the key word, which we use quite often. people don't wish to be poor but circumstances dictates they are. this applies to all, rich or poor. Just because someone is poor it doesn't mean they are not intelligent or can't make something of thier selves. Is there such a thing as middle class?
