I have to kind of disagree with the last point. We have no caste systems, culinary arts are pretty non important, and usually if people want something new they will go to a specialized restaurant. How did the USA change their culinary arts in the past 30 years?

Construction, it did change, and it is constantly changing. We used to use just bricks, now we use porous concrete, and wooden is becoming interesting aswell. We are not building skyscrapers because they are ugly.

Or am I wrong? I am from Czechia.
