I don't understand how massive corporations are both ruthless slash and burn cost-cutting profit optimizers and sloppy businessmen who don't care about the small things, even in aggregate.
What's the economics of not renting out high street retail properties? There must be millions of them across the first world, with a theoretical annual rent roll in the 11 or 12 figures. Are they owned by a million multinational conglomerates foregoing a hundred grand each? In that case we are stretching the definition of "multinational conglomerate". Or are they concentrated in the hands of the same hundred companies? In that case they are each missing out on ten billion a year in opportunity. There isn't a company in the world where you couldn't make your name as Head of Global Unused Property managing ten billion a year of revenue.
I don't have an answer for this either, but it must be more complicated than "they're all owned by multinationals who don't care about such small numbers" - the point of multinational companies is that those numbers are no longer small at scale.
