(Maybe I’m reading too much of a narrative into what you wrote, but–) I don’t think it’s causal like that; it doesn’t have to be. In particular, “wealthy, modern urban cores” tend to be self-sustaining economic force multipliers rather than parasitic resource sinks or vanity projects. Each specific megaproject might be one of the latter, of course. In general, however, I’d be careful about mixing up different public choice failures. How easy it is to: (agree on a fair way to) collect public money, identify and agree on some kind of public benefit, allocate resources to further that interest, execute projects without snags – etc.
