They are taxed, but I think they could be taxed more and better. Specifically, this community -- as the name [email protected] suggests -- is about implementing a land value tax. It's also part of a broader economic philosophy, Georgism, that seeks to eliminate monopolism and rent-seeking to create a fairer and more prosperous economy. Land value taxes (LVT) are one of the most central proposed policies of Georgism, although Georgists also advocate for carbon taxes (and other taxes on negative externalities), severance taxes on finite natural resources like oil or minerals. In addition, intellectual property (IP) reform and eliminating barriers to entry are valued. (It should be noted that Georgists want to replace bad/inefficient taxes like sales, income, and property taxes with LVT, externality (aka Pigouvian), and severance taxes.)
Yeah, only encountered a few fellow LVT enthusiasts on lemmy so far. There was a pretty active georgist community on reddit, but niche communities don't transfer nearly as quickly as generalist ones. Nonetheless, I'm trying to be the change I wish to see in the Fediverse.
