Yes, but I'm not trying to answer the question I'm trying to refute what seems to be the graph's answer to the question (that biology plays a large part). Also, I don't buy the "there were several different income level" argument. Sadly I can't find a reference on the web right now but I remember several studies from my anthropology class which said lower classes are more apt to adopt other races into their social structure (largely by necessity though it's alleged that upper classes have a subconscious desire to maintain their genetic line and hence shun those who seem different or inferior)
