It's funny you say that because in Los Angeles, mall culture is MASSIVE. Malls aren't stagnant. They are high-end and a lot of fun. Kids go there to hang out and adults go there to shop. I love it and it's sad it didn't take in other areas.
In fact, many are quite happy to visit the “Mall of Scandinavia”
And many / most smaller towns only have chains.
That Euro charm that so many romanticize is not evenly distributed.
Los Angeles probably has the most non-chain businesses in any of the cities I've lived in.
It did take for a long time in other areas. (Long = approximately the 1980s, 1990s, and 2000s.) But visits to malls across the US have been declining for some time.
