Go pick up a copy of Progress & Poverty, and you too can forward the cause (basically by annoying the living daylights out of all of your friends, like I do)

Georgism was extremely influential in its time, Progress and Poverty was the second best-selling book after the Bible and 200,000 people attended Henry George's funeral. Only it's been kind of written out of the history books since it doesn't fit easily in the socialist-communist-capitalist narrative people have in mind for the 19th and 20th centuries

The biggest marketing trick of the 19th/20th has been convincing everyone that you have to pick one of those three, or some combination thereof.
