"so sometimes it's better to preserve the valuation of your building rather than set a new market rent which will negatively affect your building valuation "

I understand that, and thus the question about WW being a canary in the economic coal mine. If there are more and more building owners who literally can't afford to "preserve the valuation" - and WW's success seems to hint at that - then doesn't that say something about the economy that aggregate numbers aren't seeing?

I understand the theory of "preserve the valuation", what I suggesting is that in reality less and less building owners are able to preserve that theory. And some of that is direct result of demand (read: the lack there of) not being in parity with demand.
