Is the Boom over?

Has the US residential highrise boom gone bust? Seems like people have avoided admitting this outright, but a pessimistic mood is prevalent on this site regarding highrise construction in this country in the near future. Anybody remember the collapse of the office market at the close of the eighties? The last towers topped out in '92 and then NOTHING for years. If this happens again then this site will practically lose its reason for being. I can see a future where the US is all but kicked off the top 100 tallest list...50 supertalls in China and thirty in Dubai, with only ten here in the US. I can think of at least 20 major, serious proposals that are in danger of being cancelled, and I might list them here or make another thread. Anyway, if anyone would like to reflect on the state of development, this is a good place to post. If you are in real estate, your opinions would be valued.>
