Spain post-economic crisis had plenty of signs to "zonas industriales" with streets but no discernable industry, as well as an abundance of ghost suburbs/towns - think that at one stage there were something like 2 million properties in Spain which had never been occupied.
Meanwhile, it seems the HEZ
went belly-up six years ago. What it gets used for now is perhaps best indicated by the fact that number 3 on the list of Google suggestions when you enter "HEZ" is "HEZ burnouts". I assume that Eddie Obeid, and/or the conga line of Hunter/Central Coast Liberals whose careers were abruptly terminated by the Independent Commission Against Corruption, were involved somewhere along the way in the debacle?
