> All of the alleged 'efficiency' gains you hear Georgists claim really mean 'middle class homeowners forced to sell their single family home to developers due to crushing tax increases'.

Not if it's paired with a citizen's dividend or other form of UBI, which is what most Georgists (myself included) advocate. The idea is that if you're occupying your equal share of land value, then at a 100% LVT rate the tax you pay should be equal to what you're getting back in dividends + public services.

LVT+UBI therefore represents a tax savings for everyone except the wealthiest of land owners.
