I'm not sure where to even begin finding numbers for people working without a degree in the same field as the typical graduate of a given major to make the comparison, but I am definitely interested in seeing the results. My hunch says that we'll find very little difference between those with degrees and those without. Unless you mean against minimum wage, but I'm not sure how telling that is. Certainly those with CS degrees will appear to be faring rather well, but that ignores that people without any degrees at all are doing just as well in the industry, and therefore are actually doing significantly better once you factor in the aforementioned costs.
