More than 30 years ago, Los Angeles Mayor Tom Bradley dreamed on an economically dominant downtown that would be on par with great downtowns like those in Chicago and San Francisco. Although Bradley's dream never came true, downtown L.A. has become a great residential neighborhood and a significant office market. It's easy to argue, though, that developers and market forces ultimately played a bigger role than government or public policy in downtown's evolution since the 1970s.
