abandoned buildings = RICH BLIGHT. If you see an unhoused neighbor sheltering on abandoned property … no you didn’t <wink>
BTW I don’t know if the phrase “rich blight” is established in any way; it’s one that I thought of and used for the first time back in 2015 when I spoke at the inaugural Elevate event in Daytona Beach. A mini TEDTalk style event.
Here’s the YouTube link to my 5+ minute talk if you’re interested. As the title suggests, I propose various ideas for “filling our empty [urban] spaces.”
