Going out on a limb, I think yourapostasy pointed to Levittown not to attempt to explain the entire economics of housing for the U.S.A. during the 70's (because hey, if we're taking the issue to that level we have to talk globally about inflation, oil, etc), but rather they were simply suggesting that, given the (in yourapostasy's ,i think correct and understated, words) "complex" issues surrounding affordable housing, Levittown is a helpful example in as far as providing a cookie cutter foundation which lends itself to indiviualisation over the long term, which is actually a more complex concept (much like building mountains or clouds out of simpler fractal shapes) than it first seems.

On point. The complexity of the overall land affordability issue isn't amenable to deconstructing in this forum's format, but yes, individualization is cheaper to accrete over time than build in from the start (especially if the labor input costs to generate the "individual differences" in the initial designs and operational implementations is driven by land costs themselves).
