Maybe one day ;)
Trust me, the people who are home owners who would pay MORE with a land value tax are sitting on gold mines. They aren’t struggling. They can sell if the cost of a LVT is greater than the property tax.
Or, they can sell land that they’re not using and shrink the amount of land they would pay taxes on. Then the cities can keep growing and people won’t be paying so much for rent.
Usually this policy reduces the amount people pay in taxes assuming they aren’t living in a 3 bedroom house on 10 acres of land in a place relatively close to a city center.
Sounds like you may need to read up more on it because you don’t seem to understand what it is.
