Explain what? Could you be a bit more vague, possibly? You're basically saying nothing here:
I spent 20 years working in such industries owning my own business, and consulting for many more, in Canada, and two other continents. I've forgotten more research than most Canadians will ever know
Well, that's nice, but ... maybe there's a separate forum for that?
And how we can sit in here and talk about buildings without discussing the businesses that pay for them (sorry, and taxpayers), and sometimes their silly ignorant administrations, is a bit strange
Maybe so. It seems to me we do discuss the businesses that occupy and sustain these buildings, and what happens to those businesses, from time to time. Mostly, however, this site is about architecture, development, infrastructure, urban history. No one is preventing any kind of discussion of 'the businesses that pay for them', nor even your work experience. But it seems like you'd rather play at being misunderstood and unappreciated.
