Also, the reason why for example Spain is so exciting visually is precisely because it mixed styles and influences over time. It's completely natural. Have you seen the Mosque–Cathedral of Córdoba? It's mind blowing, so cool.
There's only one thing that people really want to preserve, and that is the current price of their homes. US government is complicit in running this ridiculous policy of forever home price appreciation, be it via Fannie Mae or the FED or mortgage incentives or zoning restrictions.
Americans, well lets say those in the Bay Area, should be absolutely ashamed at the state of the place. There are poor regions in other countries that have life, verve, some sense of activity that "cities" all in the BA desperately need. Americans should hang their heads in shame at how uncultured and depressing the copy-paste strip malls, parking lots, shitty roads and shitty colonial Spanish architecture that screams "drought and death" just pales in comparison to Europe or Asia.
I hate living here so much.
