No way, Jose. This is not my HL Mencken rant.
I commented on general ugliness of the US man made landscape - without explicitly mentioning the reasons. But if you read my examples you will find that these include _institutional_ examples - malls, developer built Mac mansions, etc. while I positively commented on the old Victorian era architecture.
If I were to give an explicit reason - it would be crass commercialism and the profit ueber alles mentality of business and government leaders that cares only about the bottom line and does not give a shit about anything else.
