Massive demographic and socioeconomic class differences.

I worked in a city where only the very richest people could live in the very expensive high-density areas. A tiny condo being perhaps four times the cost of my very large luxurious suburban house, maybe ten times the cost of a cheap suburban house. They had experimented generations ago with high-density poor people housing; that was not exactly paradise for anyone involved, so high density is only approved if the rent will be over $3000/mo otherwise the police budget cannot handle the crime issues. There is a self imposed demographic separation where only wealthy live in the penthouses therefore being wealthy the prices charged to fit their budgets are high. Of course there are maybe 1000 suburbanites for every CEO in the nicest five million dollar penthouse. And the population of the burbs combined is approximately 20 times the population of the high density areas. Its possible to cheat such that you are "in the city" but in a tiny house near the dangerous part of town that hasn't been gentrified into unaffordable condos... yet. But I'm not counting SFRs as "high density urban" because its basically substandard suburban lifestyle.

Housing projects are another question altogether, since people who live in subsidized housing don't really have the same choice and don't participate in the market the same way.

Let me ask you this--why don't the very richest people in your city live in very expensive suburbs instead of very expensive high-density areas?

Don't they? The only rich person that I know that lives in a penthouse is the dropbox CEO. Bill gates, Jeff Bezos, Andy Jassy, Mark Zuckerburg, Larry and Sergey all live in suburbs as far as I know.
