Intellectual property is seriously changing the subject. Capitalism got along just fine (or not, depending on your view) for centuries without it, and then with copyrights, trademarks and patents, each of which has an obvious functional utility and definition.
'Intellectual property' is a catchall phrase invented to allow immortal coporate entities—which are incapable of intellect at all—to own ideas forever, and charge us for them. Didn't even exist as a phrase until today's media exposed the money-making possibilities of leasing expression. Best leave it for a topic of its own.
Actually, intellectual property has a history that goes back over a thousand years. Our old english ancestors would have called them "choses in action."
And in today's economy, it is critical to first world countries. Due to our standard of living expectations we cannot compete with places like China is making shoes, T-shirts or other labour intensive items. One of the key ways that the first world competes on the global stage is being able to leverage our capital and technology advantages in making drugs, movies, computer parts, new technologies etc. But if there is no way to "own" these things and profit from them, then there is no way, in a capitialist system, to motivate people to make them.
Part of a capitalist economy is a system that protects property rights. Whether they be land, or the chairs you just built or intellectual property. A capitialist economy needs those enforcement mechanisms.
I simply don't accept that China is a capitalist system or it is a more capitalist system than most first world nations. Or perhaps more accurately they chose not to be part of the international capitalist market.
And I hate to have to correct you again, but intellectual property protects and has always protected, writers, photographers, dancers etc, and is not simply the realm of big companies.
The other part of the argument that appears wrong becomes clear when we look at why China has done so well in the current economic crisis. It is the state owned part of the economy and the huge programs run by the government that have helped China weather the storm, not the capitalist part of the economy. They simply control various prices (ie fuel) and have spent "stimulous" money that has driven the economy. These are not market solutions, rather command economy solutions.
