All important architecture of the last century was strongly influenced by political systems. Look at the Soviet system, with its constructivism and Stalinism, Weimer with its Modern style, Mussolini and, of course, the Nazis and Albert Speer's colossal structures. Today's architecture is subservient to the market and its terms. The market has supplanted ideology. Architecture has turned into a spectacle. It has to package itself and no longer has significance as anything but a landmark.
Rem KoolhaasI studied in London in 1968. Our school had a separate department of tropical architecture. Of course it was totally unfashionable, partly because nobody wanted to think about colonialism, but basically what you learned there was that, OK, the sun is here, so you should create natural ventilation here - an unbelievable amount of really sound principles that have been completely abandoned, so now everything is air conditioned with big machines.
Rem KoolhaasThe Metropolis strives to reach a mythical point where the world is completely fabricated by man, so that it absolutely coincides with his desires.
Rem KoolhaasLet's put it this way: One can be happy or unhappy in a building. But some buildings make us more depressed than others.
