There can be two scenarios. In capitalist system, we will be having 3 classes of people - around 5% who are rich, another 90% who are in the middle-class with a relatively comfortable style of living, and then the remaining 5% comprised of "poor" people. The in socialist system we will have only two classes of people - 1% of the population will be ultra-rich (mostly the ruling elite) and then the remaining 99% of the people will be poor. It is up to the people to chose which system they want in their country.
