The Torah values equality in the application of the law. Thus we are enjoined from treating a poor man or rich man differently in terms of halachic decision-making, or taking bribes.
Pirkei Avos also speaks of loving all creatures and bringing them closer to Torah. And Hashem is pleased with someone with which others are pleased. This implies we should be kind to all people regardless of who they are.
Absolute economic equality is not a Torah value. However, the highest level of charity is to ensure that the poor become self-sufficient. So ideally, if we were observing the mitzvah of tzedakah correctly as a community, everyone would be equal in the sense that we are all self-sufficient and do not need to rely on charity.
All Israel have a share in the world to come. And Rebbe Nachman teaches that everyone has the innate ability to become a tzaddik of the highest order, if they would only apply themselves with their greatest effort.
