I have never understood why there is an expectation to treat everyone equally when people are very unequal, from their birth circumstances, which obviously they can't control, to their behavior as adults, which people do have control over. People don't treat me like Michael Jordon because, guess what? I cannot do the things he does. It would be rather silly for me to get all in a huff because I don't get the treatment that celebrities get. Another example: a single teenage girl has a baby when she's 15 and two married computer engineers have a baby. Does anyone really expect that those two kids will have equal opportunities? Is it our society's job to ensure that they do? Should we limit one kid's opportunities if society can't provide them to the other kid too? It sucks that some kids are born into less advantageous circumstances, but it's the way the world works. Sometimes it's because parents make bad decisions, sometimes social systems are unfair, sometimes it's neither; luck of the draw. It's funny to me that everyone seems to think diversity is a good thing, yet at the same time want everyone to be the same.
