As someone who is just coming to the end of his architectural education and having worked in the industry for about 7 years now I can say this is largely a problem with academia in arhtecture which sees itself as some kind of pseudo-philosophical subject. Building regulations in most countries that I have worked in, for better or for worse, will not allow for architects to pull off what the modernists or the post modernists did anymore. (This is not to say that there aren't people out there still churning out poorly thought out buildings)
