Pat Gunning and Warren Samuels have referred to "taxing the unearned  
increment" which from a Georgist perspective makes no sense to me. I  
don't recall George ever using the term "unearned increment" while he  
did advocate collecting all or almost all of the ground rent for public  
purposes at the same time eliminating all taxation of labor, capital and  
the wealth produced by labor and capital. Wasn't it Mill who proposed  
taxing the future increment in land values?  
  
What has not been mentiioned in this thread are the economic  
implications of land speculation. Since the selling price of land is  
ground rent not collected by the public or the community capitalized, it  
results in a very substantial speculative or anticipated ground rent in  
addition to actual ground rent received by the landowner.  
  
Just wondered if anyone considers entrepeneurship a fourth factor of  
production beyond land, labor and capital. Or, is an entrepeneur just a  
more skilled  or knowledgeable laborer?
