Here's a randomly picked example: http://paulgraham.com/inequality.html
Randomish quote from end of article,
"The problem here is not wealth, but corruption. So why not go after corruption? We don't need to prevent people from being rich if we can prevent wealth from translating into power."
Umm... how about in a capitalist society money is the vehicle of positive freedom... to increase ones ability to do something on has to have more money. Therefore under capitalism there is always a fundamental tie between money and power.
That's a small off-hand point.
But if you have any serious reading on the last two hundred years of economic, political and sociological critiques of capitalism, wealth and power that whole article will just seem silly.
I'm sure he means well. But it takes a certain kind of "pseudo"-something to think that this kinda hackney "thought-lite" material should be delivered at a major conference (Defcon 2005). If i were asked, on the back of my reputation, to speak on this, I would at least spend a week watching/reading/etc. as much as I can in the area.
