Drew, the only alternative to a capitalist system is some form of authoritative regime... however, it need not be limited to authoritative redistribution. In either case, the problem that most people have with alternatives to capitalism is the authoritative-ness not the redistributive-ness. It just happens that most justification for authoritativeness comes from redistribution schemes. I made this argument in the previous post.
Of course, I think it worth mentioning that I like the current system of the US mostly and I would much like to see the system being improved by becoming more capitalist.
In any case, I think it important to point out that the observation that people need things to live is trivial. There seems to be an assumption that, somehow, I'm denying this... which is not the case. Of course people need things to live. It would be downright silly of me to refute this and it would be silly of you to think that I don't understand this.
My point on this issue is that while people need things to live, people also need to produce the things that people need to live. Both statements are obviously true. I don't think you would even attempt to deny my additional observation... but what do these things prove? Nothing. These will be true in any system. Whatever the system is there must be producers for there to be consumers.
The thing that we're arguing about is whether anyone's need provides sufficient justification for the use of government power to provide it.
I'm not sure you understand the difference in the nature of control within the capitalist system as opposed to outside it. Within the capitalist system, you may be thinking "I don't have control", but this is technically true of everyone. From producers to consumers, nobody has full control of anything. That's kind of the idea. The price itself is a reflection of a huge variety of factors... the most important of which at this juncture is the relationship between the needs of people and the available resources. The reason the price elasticity of demand behaves the way it does is because everyone needs these things. Of course, I think you've blinded yourself about what happens on the supply end when the price rises. The increase in price is what drives investment in developing new resources, infrastructure, and methods that previously were not profitable to respond to the increased demand. Every great profit represents a great need for new resources to be developed.
Price controls prevent this from manifesting and retards the growth of sectors that need to grow to fill demand. In other words, this is not a viable solution to any problem of shortage (the root problem of rising prices) as it greatly keeps down the ability of specifically new competitors and even existing competitors to spend the money developing new infrastructure and forging new methods. The price itself is a manifestation of deeper issues in the overall market, to ignore this is to break from reality.
To put it another way, a car costs so much because people value it so much. The cost to produce is irrelevant... I'm sure it'll seem silly, but it is worth mentioning that people are fully capable of valuing things at less than the cost to produce is, people just aren't in the habit of wasting resources producing these things (well, unless it's like valuable in other ways, but that's why there are non-profits).
Now, let me address your "lack of freedom" again... the lack of freedom imposed by a capitalist system is the lack of the ability of any one person to name the price. Just because I don't feel a car is worth $20,000 doesn't mean the guy next to me agrees. Of course the seller is going to sell to the guy willing to pay more. And it is right that he does. It would be selfish and irrational of me to expect that people producing the thing should trade it to the person willing to pay more than me. It would be equally selfish and irrational of me to believe that the people making bread, cars, and other necessities DO SO FOR MY SAKE. The world doesn't revolve around any one person.
The thing you need to understand is that those "market value" represent the "social value" of a product: the relative value assigned by all producers and consumers competing, negotiating, trading, etc. The value something has within the society. The fact that the cost to produce isn't much compared to the value of the final product just goes to show the value of actually producing the good. The "fairness" of the capitalist system is that the "market value" of everything I put into the system as a producer corresponds to the "market value" of everything I take out as a consumer. Can everyone add a value equivalent to the value of everything they need to live? History shows this isn't always the case.
Now, I'll take your argument on people experiencing life as they want as a hyperbole... the society at large is better off if those kind of people who expect other to provide their life and comfort for them to be ignored. Essentially, there is little reason to keep such parasites around. That's not the meat of the issue though.
For those who are unable to provide for their own needs, I wouldn't use such harsh language, but the sentiment isn't all that different if they expect that others provide for them. This brings me back to the compassion point. I don't think you truly get the picture of compassion. It is easy to just say, we should pass laws to feed the poor and leave that responsibility to the government... which while I don't think it is justified, there is a deeper thing that I take offense to. That is the notion that the fulfillment of your personal values is somehow is not your personal responsibility. To say that the government should provide the necessities for people is one thing... to actually provide the necessities for people is another thing. I think you can see where I'm saying it's only compassion if you earned the money you're giving to others. I heard a slogan once that "Profit precedes Philanthropy", in other words, the idea I'm trying to get across is that you need to actually create the value that you give to other people. I think it shouldn't be too surprising that I accuse you of being more concerned about depriving the wealthy of their money than providing for the poor. You don't want to actually be inconvenienced to help the poor, you just want to feel smug by ordering others to do it for you. That is essentially what it means to say, "the government should provide for people." Everyone knows that we all can help each other out our own damn selves and we don't need the government to do it for us.
