Greed vs the Skyscraper!

Heres a thought I recently had. As company's continue for ever higher profit margins, cutting overhead costs, moving administration to cheaper labour markets abroad and encouraging those who can to work from home with the advance of electronic communication e.g e-mail and the internet, the need for office space will decrease, this will mean a drop in demand for tall office buildings. This same greed (higher profit margins) will not only affect the administration side of business, as industries also transfer their labour to overseas cheaper labour markets and with the advance of machinery taking the jobs of the workforce this will mean more people without employment, and this in turn will affect the demand for expensive residential high-rise. Do you see where Im going with this? The only way out of this of course is for those at the top of the ladder to except lower profit margins they no doubt will still be earning millions each year just not as much, and in return will retain the demand for high-rise construction and possibly far wider consequences. What do you think?>
