I am saying that they are useful to society. Quite necessary to modern economics and standards of living, actually. They are not the best possible of institutional arrangements at all times, though. Look at how many more sole proprietors and partnerships there are in the world, even in economic powerhouses like the United States.Now you could argue that despite being corrupted or subject to institutional malaise corporations are the best possible of all possible institutional arrangements but I dont think you're arguing that.
I am not partisan in favor of corporations at all. Look back over my posting history and you will see how I criticize corporations for using the government and collusion to game the system to their own benefit. I reference Gabriel Kolko regularly. The criticism "partisan in favor of corporations" is silly. The equivalent would be saying that I am partisan in favor of people or horses or boats. The bottom line is that many of the critics of corporate behavior are off-base with their criticisms, and it often stems from a juvenile and economically tone-deaf view of the world.Yeah, it sounds like you've encountered some sloppy thinking about externalities, in fact it seems like you're pretty partisan in favour of corporations and apt to react a certain way to what you preceive as criticism of them. It doesnt mean there's not an issue with externalities, whether its the people you imagine to be morons or villains which are mentioning it or not.
I am a supporter and defender of free market capitalism, and I wish the world (especially the United States) moved more in that direction. I do not like the unholy union of Big Business and Big Government that we have endured for the past century or so, and one which is rapidly accelerating under Obama.I'm not a supporter or defender of capitalism but I would agree that capitalism's supporters and defenders have been much more articulate and clear than their opposite numbers and detractors. Although being good writers doesnt make them correct. At least not all the time.
