why no longer matters.
Detroit has fallen.
Detroit is done. (put fork in it done)
call it the lost city.
call bankrupt
call it a former city
none of that matters.
there is no money in detroit.
the bond holders are going to recieve a serious haircut or they are going to recieve some serious amount of land.
If Dresden and Hiroshima can be rebuilt, so can Detroit. It might be a good idea to populate the area with Germans or Japanese though if you expect to get any work done. Perhaps sell Belle Isle to the Taiwanese or Koreans?
