But who gets to rent out the apartment building? Well, the one who put an apartment building there, that's who. Why should anyone else get to?
Now, I am not saying that the building itself doesn't have value, or that the person who built and owns the building shouldn't be compensated for that investment and work, but it is disingenuous to pretend that the majority of the value is from the building and not the land itself (at least for most places where rent is high)
I am not in any way, shape, or form arguing that we should seize all private property in some kind of communist revolution; I am simply saying we need to think about how we divide up the value of something like real estate to fairly compensate and encourage development without promoting unfair and ineffecient rent seeking.
In most areas, yes. There is a property tax that is charged as a percentage of the land's value. If the owner fails to pay this fee to society, society revokes his ownership, forcefully seizes the land if necessary, and resells the property to another person who is willing to pay the imposed fee.
We also do have taxes on income produced by capital - that's capital gains - but, as the article points out, we tax them significantly lower than regular sweat-of-the-brow income, and offer more loopholes. In effect, our economic system incentivizes rent-seeking over labor.
Yes, a piece of property earns rent because it has 'value' to someone else; however, who gets to earn that value? At some point, this piece of land was 'unowned', and then someone came along and said 'I own this'. Do we let them keep that forever? Do they have to pay society a fee for being able to claim it as their own? Can they give it to their kids for perpetuity? Can they do anything they want with it? What about the air above it, or the ground below?
These are all very important questions, and there isn't some 'true' moral answer to them that is the right way to govern property rights. There are easier moral arguments to make about ownership of property I produce, but not about land or natural resources.
