We can talk about the crazies at the microphone till the cows come home. One thing we do have to keep in mind is that those crazy individuals will rarely have an impact on our lives other than to be stupid in public and either enrage or embarass us.
What of the brain-dead folks who have a real impact on our lives and who rarely get called on it? Like developers who abandon architectural utility in order to turn a quick profit? My new sage GulfSails has some great thoughts on that particular discussion here.
There's a reason I'd rather live in a hundred year old house rather than a 40 year old house, and that's got as much to do with asthetic-as-utility as it does with historical preservation.
