Why love each other? Why be equal?

How should we treat the people that are "less" than what is "better?" Politically speaking, equality is an ideal that everyone knows isn't true. We are not all born with equal opportunity. People are a product of their environment. If all you know is violence and drugs then you can expect a person that grows up in that situation to reflect that. It's not their fault. It's not like I get to choose what family I am born into, or what school I go to, whether it be a nice suburban school, or some inner city school. I would be curious to know, blappers, (If I am not getting too personal) what your theory on ethics is? I do have to say that I disagree
