      My new favorite example of infrastructure cost disease: construction of the Eiffel Tower cost $40 million *in 2019 dollars*. (Also, it took 2 years and 2 months to build.)

      Tokyo Tower: $26 million present dollars (back in 1958). I think that Japan could still do it for about $100~200 million today, but my confidence in that estimate is low. (How strange that 4X~8X disimprovement in 70 years sounds like bragging...)

          What are the biggest contributors to this cost increase? Permits? Materials?

          I'd attribute almost all of that to the wage premium for skilled and semi-skilled labor in Japan in the present day versus in late 1950s. (Wish I had a convenient cite for you but accounts of that construction project make it very clear that Japan was not a rich nation at time.)

          They talk about that with the GGB and the Empire State building too. One difference is that many people died when we built those structures. One could argue that each life saved now is worth significantly more than the $ and time saved then.

          Only 11 people died building the Golden Gate Bridge. 10 of the 11 died because a safety net snapped. Not bad for 1937 standards.
