I don't know how one would even think to graph these two variables, but it is an interesting picture of the life cycle of development, where infrastructure improvements are initially an important part of the development equation, and then fall off, percentage wise, as wealth is enhanced with softer goods.
Anyone off the chart on the high side are going to be what I would call the triumphalists, who do what Thomas Friedman seems to want and pour a disproportionate share of money into high-visibility monuments (e.g. tall buildings, dams, bridges, high speed rail, etc). I don't see Dubai on here but if they were they might be off the top of the chart.
Zero Hedge links this chart to make a point they have made for a while about a massive bubble bursting coming soon to China, a position with which I agree (though the timing is always a question in such things -- the state has the ability to delay the reckoning at the cost of a worse crash when it eventually comes).
Disclosure: I am short Chinese real estate and stock funds.
