Your analysis is only applicable to a free market- not the Republican kind, the left libertarian kind. In the real world, there are artificial barriers to entry, tax barriers, charter, license, regulation, etc. ad infinitum which hurt the poor by either robbing or restricting them in some way.
Your analysis only applies to free markets, not to the system we currently live under.
To expound on this idea, the free market talked about is one without any laws or restrictions. A market that has $0 artificial cost to entry. The type of a market that's only possible in theory because people like the idea of governments saying, "No, don't make stuff that kills people. Or maims them horrible as they go for some ice cream either."
In reality, consumers are so massive (in number, let alone weight) that they almost are fixed with regards to their consumption. And it is not, in fact, consumers who dictate what is good or popular or whatever. Never has been. There has always been someone else not in the same consumption chain telling people what is good.
Take (really random here) champagne for example. Rather than lowering the cost per bottle and selling the same number of bottles, thus deflating the chance for future profits, vineyards are simply making less to keep prices high. There's a two way relationship here with regards to supply and demand, but it's not the textbook relationship. Demand went down, due to the economy. Now, supply should stay the same with prices going down to achieve an optimum efficiency relationship. But it didn't. The champagne growers all got together and decided that if they dropped the prices now, it would be hard to raise them in the future.
Why? Because people are people and not spreadsheets. So, they let 30% of their crops rot, produce at inefficient levels all to maintain price levels optimum for future levels of demand. Consumers are a factor, but the benefit to consumers isn't.
