There's a different between trying to preserve inequalities and not bothering that they are there. The latter was my point. I never said don't bother working hard because you might as well stay poor. Those who can and choose to will work hard to give their children the best start in life whether that's good food on the table, school fees or whatever you can afford.
People are very different from each other. Isn't that inequalities? Some of us are clever, some not, some pretty. It's all just an accident of birth.
Why is altruism the natural order? I thought that had been found to be untrue? We might help the sick so we're helped when we're sick or it may be in the interests to look after those we care about because that benefits us but I don't think it's natural we might for example give away all we earn or share within a group. Whenever that type of communism has been tried it's failed.
