The lives of the underclass people

From birth, we are always learning. Of course, we also know why we learn these things. Starting with crawling (that's an instinct), we crawl in order to walk upright; when older, we learn how to speak in order to communicate; when we start school, there are many subjects so that when we grow up we can have a good job and a bright future; when we grow up, we work in order to establish a family and a career. Now we've started working, after several years of working, without having established a family or career, we work just to be able to survive in this city.
