With no doubt traditionalism. In architecture it is hugely important to culture, it also looks respectable. Why? Probably because those Who were paying for the buildings were not Scrooge level of über greedy like most of them today, plus the current cultural status was not dragged out of the sewer!
For the ones paying for the building, modernism is just a word for make it as cheap as possible, and for the architects it's a competition to be as unique and artsy as the can be. It is disgusting, and everyone who does not like it has to suffer for it, since nine out of ten buildings being build is modern, hope to god that will change
This thread would really fit having a poll.
