Back in the 1970s, a lot of publications reported on Gerald K. O'Neill's ideas
for space colonies.I was thinking about the illustrations (which always showed pretty and clean little towns folded into the cylinders) and something occurred to me. Am I right in thinking that the people in those illustrations were invariably white? Because I read a
lot of this kind of thing in the 1970s [1] and I can't recall any crowds scenes that were particularly diverse.
Obviously one market for O'Neill colonies is to provide a refuge for an extreme form of white flight but I am a little surprised that the illustrations would be so blatant about it.
1: There's no real need to buy any book on the subject more recent than, oh, 1980.
