The problem I have is with phrases like "I would bet there is" or "I assume those blacks [with white sounding names] are more likely to come from families that are wealthier and better educated."
It seems like an obvious correlation to make, but they're not based on data. I think it's in our best interest, intellectually, to take a few minutes and look for some information. The internet means it can take fifteen or twenty minutes to find a decent chunk of data to start working with. It won't make you an expert (and I'm by no means one either), but it can help highlight a lot of the nuance that exists in issues like this.
