I know this isn't something that can be well-covered in a blog, so I'll keep it simple.
Capitalism, is not the practice of taking all the profit one can and keeping it. That's called theft. Capitalism, in its true form, is the practice of taking your resources, investing them in your community, and enriching as much of the community in the process as possible. Before capitalism, the western world essentially worked on theft and one other social/hierarchical structure, serfdom.
Serfdom is the practice allowing some of the community to use your resources, while you keep all the profits. Many modern corporations use this model. Like lords of days past, they distribute the profites to an elite class of property holders, save that they cannot keep due to theft, and the nasty habit serfs have of dying if they're not fed.
The modern improvement on serfdom that has allowed the corporation to blossom is called the "stock market" wherein the elite ruling class persuade the middle and lower classes into returning their profits to the corporation, in exchange for the belief that their own prosperity is tied to the prosperity of the corporation. That's a whole 'nuther article.
Modern capitalism, in most cases, is simple theft. The "willingness" of the client to purchase does not make profit-taking less than theft. We all learned this when we were three. If you traded the retarded kid in kindergarten a booger for his lunch money, you'd have to give it back. If you traded Suzy an iPod for her dead grandmas diamond broche, you have to give that back too, even though Suzy might *really* like the damned iPod.
My point is this: Capitalism is not a dirty word, being greedy and taking more than you need is wrong, and most importantly, all our good fortunes depend on the good fortunes of our neighbors.
