I guess there is still discrimination between different cultures in Australia. Although our indigenous people are respected much more than during the last couple of centuries, I still get the impression that we are not fully equal with them.
While we can acknowledge that there might be a select few who have worked their way up from scratch, its only a small minority. Whatever opportunties were taken to get them there, they dont come along frequently. This minority still doesnt change the fact that people from poor/lower classes on average have less opportunities than someone from an upper social class.
