>But homeowners would likely be willing to share value too
No, they wouldn't. That is why property tax rates (and hence land value tax rates) have so many laws capping them and otherwise limiting them for all the important voting blocs (old people, military, big business, etc).
See California prop 13, that voters passed. See Oregon measure 5 and 50, also passed by voters. And politicians wouldn't dare touch these.
>In American cities, there is an issue with value capture. One party creates the value (in this case retailers), another party (landowners or homeowners) captures it.
This phenomenon is not restricted to American cities. It will broadly exist in all human societies with flattened or top heavy population age histograms. The old are the most populous and knowledgeable (and motivated) to structure society so that the non working (themselves) can capture the most value. Hence, the popularity of earned income tax instead of marginal land value tax rates. The goals of the wealthy and the old (and the ones with aspirations to be wealthy) align to support rent seeking policy.
A perennial cause for revolution around the globe.
It’s a bit ironic. In an effort to horde wealth, the wealthy bring about their own ruin. Though I suppose if you die before the revolution that’s alright for you
Apres moi, le deluge.
Revolution has never changed this status quo. Just results in violence, then once the ship rights itself the social order is back to how it was with an oligarchical elite extracting value from labor. In fact I don't think there has ever been a single case of labor unshackling itself from the yoke of the oligarchy.
If there is a natural human condition, it must be this, just because of how sustained this pattern has been over the course of what tens of thousands of years to today, even in the face of modern technology and more universal awareness that this is how the world actually works.
