Right on about sunk costs and too true that we hang on to those, and sometimes make bad decision because we cannot let go. But you seem to conclude that the main objective of an alternate transport system is not needed. You suggest no alternative actions. You seem to leave the commuters in Ewa area without hope. In retrospect we should have only allowed truly affordable housing to be constructed within a reasonable distance from major employment centers (downtown, Waikiki, Ala Moana, etc) and schools (UHM, Iolani, MidPac, Punahou, Chaminade, etc., etc.) but we did not do that and instead created more affordable housing 2 hours away during rush hours which has left people to commute for 4 hours daily. What would you do about that situation of today? Are you suggesting to demolish the HART portion which has been constructed? I wonder what is the economic cost-benefit of demolition of the constructed portion vs. redesign to take it to other locations? Stopping now is not cost-free.
