Just a guess, but it seems like a lot of the commenters here don't actually live here in NYC. I, for one, like tall buildings, but I also like to see the sun from time to time. Considering that it is unlikely that the particular building mentioned in the post will be the last to be built here, perhaps talking about this is a way to make builders and policy makers consider the effects of their profitable ventures on the other people who live and work in NYC.
Hmm, that's too long and doesn't seem to fit in with the tone of the discussion. How about this:
Nice to see BBers think only people who can afford million-dollar vacation homes should be allowed direct sunlight.
