But see, Phil, I don't think what you are talking about is double standards - not as I define it. Treating people differently based on ability is not double standards, it is different standards. In a basic definition double standard can just mean different treatment but it is more commonly used as a negative term and implies an unjust different treatment. And, knowing Drifter, I have a feeling that it is that narrower definition he's talking about.
What I believe he means (correct me if I am wrong, Drifter) is that he does not want to apply any 'rules' to others that he would not apply to himself. I don't think he is talking about society as a whole but just his own life and the way he leads it.
To answer the OP from the pov of that interpretation, I would say yes, it is possible. It is undoubtedly very difficult though. The main reason I believe it is difficult is because it is so much harder to understand the motivation of others when they do things that I see as unfair. Whereas when I do something that others might see as unfair I am in possession of all the facts, all the background, as to why I made the decision to act that way. The way around this I try to take, and Lord knows I'm imperfect and fuck up often enough, is I try very, very hard not to judge and also to remind myself that I probably do not know the full story.
Edit: And I really don't see what money has to do with it. I don't see why one would have to be 'financially independent' to live a life where you accept that if it is OK for you to do something then it is OK for everybody (or indeed if it is NOT OK for everybody then it's also not OK for yourself).
