So capitolism is a sort of organized greed, where freedom is found in financial independence. When the number of principles in a financial undertaking is limited, and there are real people in control, the system works well. As the number principles grows, and the endevor is an amoral quasi-citizen (a corporation), the system optimises for greed efficiently. Corporations do not value society, except as a means of production and consumption.
Corporations grow by nature, and only have a conscience when it fuels growth -- at least on average. There are exceptions to the norm, as in nature, but the good companies stand little chance against well-optimised money making machines in the long run.
Business is applied greed, though we're generally fine with it as long as we gain from it. As long as the majority gains minimally, the whole system works. Alternatively, as long as the majority is enslaved (even if under marginal freedom), the whole system works. Our world is generally a balance of these two approaches. And we're generally fine with it if we have our computers, big-screen TVs, and other middle-class wealth.
Just like me writing this on my stupid laptop, thinking about how globalisation is killing the little software company I'm at, and how we should really be fucking happy to be eating ... rather than worried that we won't be able to buy our yuppie shit.
