Great essay, but I’m puzzled why you started with Mexico 1968, rather than the Tokyo 1964? Surely a more logical starting point given the points you make, and a missed opportunity to compare and contrast the two examples. There was a huge investment by Japan in the 1964 Olympics — commissions to some of the best Japanese architects of the day, and a not bad identity and icon system. Many of these buildings stand today and are well worth visiting.
