That's what has been said before, in and out of this thread, about the changes in malls everywhere: what is in crisis is the mall and big shopping centers in general as centers of consumerism for anybody and anywhere, mainly middle and lower classes, while upscale or very specific projects developed by powerful companies are booming, oriented to a very specific, more profitable part of the market.
In fact, that leads us to the general trend of the economy: in the post-war model, that of the old malls and shopping centers, the strategy was that of proselytism, to call for everybody to jump in the wagon and make profit by adding cent to cent, which in fact was the way of the first greater centers, from the French and British first department stores in the industrial, second half of the XIXth century, to the Woolworths and Wal Marts in America, while today projects are developed following optimization and targeting consumers who throw you directly in a bulkier and more profitable balance sheet.
That gives you one reason of why I always say that the XXth century is on its last legs, is also what can give you a better understanding of what is behind that catchphrase of the middle class being squeezed, and of the wealth gap widening, and what is giving you an idea of what the real XXIst century would be about.
In any case, apart from all that, when in considering those new and more or less ambitious developments, you do not need to believe they are meant to be thought as investments in the long term...
