May I suggest that if you've not read Henry George's thought yourself yet, you take some time with them? There are two sections of the Schalkenbach site devoted to them -- first, the books, articles and speeches themselves, and then an introduction to HG's thought, with perspectives from a number of writers, mostly recent. With the latter group is a short version of Progress and Poverty entitled "Significant Paragraphs."
His vision and clarity are remarkable and inspiring. 120 years ago, his ideas were widely understood throughout the English speaking world. (There were also a lot of hilarious misinterpretations by people who hadn't read, as is often the case.)
And if you explore a bit, you'll find some good websites and blogs devoted to his thought.
