At a time when businesses are going out of business, cleaning out their stores in strip malls and multi-level structures, eventually producing a glut of buildings that nobody will want to occupy, and thus those who own those buildings returning a loss on capital, we don't need new buildings right now. Schools are an exception but not really, except for some in major cities perhaps.
We need to cut government spending right now, not increase it.
The situation is national, if not global, but it reminds me a lot of Texas in the early 1990s not long after the S&L scandals. My younger (ninja cop) brother moved to Austin, and miles all around you saw nothing but half-built strip malls, abandoned housing developments, etc. That stuff is boom-and-bust cyclical.
That said, we probably need a lot fewer buildings in some places and more in others -- and with specific purposes in mind. Just less overall.
Lately I've been pondering dead societies and cities -- Persepolis, Palenque, Palmyra, Ephesus, Angkor, Vijayanagar, etc. -- and some of the modern equivalents we might consider today -- Detroit, Asbury Park, NJ, North Dakota, etc. We often forget how climate and economic shifts have created abandoned cities throughout history.
