I’m not sure if you’re addressing the entire article when you say “that” or just this line. I think you are just teasing out this one issue here. And to your point, I’d agree. When I moved here in early 1971 for the first time the city fathers were bandying about a light rail system. That didn’t happen until about three decades later, and by that time it was vastly more expensive, vastly more difficult and too little too late. However, without the influx of new residents, you don’t have demand. As long as someone can make a buck selling shit housing they will build it. In this case it’s a reverse of the Kevin Costner line, Build it and they will come. In many parts of America, they are coming and now they have to build to accommodate. Part of this, to your point, is the utter resistance that so many people have to welcoming newcomers. They’re coming anyway. But the denial of that fact has left cities and towns woefully unprepared. Bad urban planning is a fact of life in many many countries, not just ours. Greed rules- and greed is what creates ugly neighborhoods and blighted countrysides.
