"The people that walked in darkness have seen a great light"

Have the great bastions of economic neo-liberalism suddenly seen the light? The Forbes Magazine produced a truly astonishing tweet:

"Contra Piketty It's Not A Wealth Tax We Need But A Land Value Tax http://www.forbes.com/sites/timworstall/2015/03/27/contra-piketty-its-not-a-wealth-tax-we-need-but-a-land-value-tax/"

The accompanying article is just as surprising. In it, Tim Worstall lauds the ideas of Henry George, saying "A land value tax is a thoroughly good idea anyway so let's get on with it".

Simultaneously the Economist seems to have stumbled across the name of Henry George (who in his own time was better known than his contemporary Karl Marx), see "The paradox of soil" from this week's issue. Key quote: "they could heed the advice of Henry George, an American follower of Ricardo who in the 1880s made the case for a land-value tax".

The people that walked in darkness have indeed seen a great light. But are they too strongly tied down by self serving neo-liberalism to act?
