Speaking from an outside perspective; malls (what we call shopping centres) in Australia didn’t die anywhere near what has happened in the US. We have a very different geographic landscape (hyper-concentration of population in city centres) and definitely don’t have the same level of penetration that companies like Amazon do, but we have shared a lot of the same economic headwinds that the US has. From my armchair perspective, this would generally suggest that it’s less to do with economic position and more to do with idiosyncrasies of the US, but I have absolutely no data to back that up.
