This is the best response I&#x27;ve seen so far. Real estate is actually a great <i>export</i> for cities and countries, at least properly considered: <a href="http:&#x2F;&#x2F;www.slate.com&#x2F;articles&#x2F;business&#x2F;billion_to_one&#x2F;2013&#x2F;11&#x2F;billionaire_apartments_they_should_be_an_economic_boon_to_cities.html" rel="nofollow">http:&#x2F;&#x2F;www.slate.com&#x2F;articles&#x2F;business&#x2F;billion_to_one&#x2F;2013&#x2F;1...</a>.<p>Seattle has a bunch of similar articles about &quot;outsiders&quot; supposedly driving up housing costs. Which is absurd: steel frame construction and elevators are very old technologies that allow humans to build just about as many housing units as can be desired.
