@Reelya,
Makes sense! At least academically, but just because the market as a whole operates as a distributed network doesn't mean there aren't players who are so large that they break the model. At least in the self-regulatory sense. Unfortunately, those transgressions rarely get transferred to the consumer (although artificial scarcity and raising prices to falsely imply higher quality or status is a common enough tactic that is frankly, predatory) and instead get dropped on the newest or lowest employees.
Look at Walmart, very competitive from a consumer's point of view, but those cheap prices and volume of product are reliant on a combination of terrible worker conditions (allegedly at one point 70% of new employees left within the first year?), shifty and dangerously monopolistic agreements with their legitimate suppliers (usually to the supplier's detriment), and literal slavery from their overseas ones. And as an American, we ARE very reliant on these types of corporations, but their ease, and excess, and success are based entirely on crimes committed elsewhere.
THAT is what I am getting at. It's almost not-Capitalism, sure they're playing the game within the rules, kind of, but it's like min-maxing a character in a poorly designed RPG, you're just breaking the game using tactics bordering on exploits. Nothing about how large corporations operate reflects a system that is working. Period.
To reiterate earlier, economic theory, ESPECIALLY capitalist economic theory does not do anything to raise the quality of life for those who buy into its system. All the achievements in the rise of the quality of life in the US have been largely incidental to economic progress--and sometimes directly opposed to it, and instead achieved through political reform or exceptional crisis, usually the latter.
Also, the reality is that bargaining, collective or otherwise, is suppressed. It is not a neutral system, and indeed favors the company over the laborer. Make what claims you will about the availability of labor, but it shouldn't work that way. Like I said, the social contract, no one is so unequal that they should have to BARGAIN for a basic life (and income is life in most places), let alone a good one--corporations have too much power and are in many ways treated as if the corporation is the King of some self-encompassing feudal realm or somehow alive. That shit needs to stop, it's not so easy to say "I'll just go somewhere else".
ALSO, if we are referring to investors as Capitalists, it may or may not be true that they are calling the shots. Some of them DO make the pricing decisions, quite frequently, or impose their influence to the same effect. Those agents to which you are referring are not always so free to respond to change in a "natural" way.
In conclusion, what I'm trying to get at here is that Capitalism is an academic theory and the reality is that it's quite broken in operation, which is why changes need to be made. Even if it wasn't, I would still advocate for social democratic intervention (as a first step), because a reactive system like Capitalism will always leave people out to dry when the going gets tough, regardless if there are people breaking the rules or not. Planning doesn't have much to do with it, I only brought it up in the first place (and maybe I should NOT have) because I wanted to point out that the accumulation of significant amount of economic decision making power ANYWHERE will lead to abuses.
