Gas prices

I have noticed that many people are interested in gases prices and what they are/could be doing to the less fortunate of our great society. I have also noticed a lot of commentating that revolves around free trade, people who want gas will pay for gas while those that do not want to pay for gas wont. While this sounds good in theory this leads to the poorer sects feeling vastly more pain then those that are more fortunate. While I do not wish the government to give hand outs to the less fortunate simply because they do not have as many resources as others, I do want something done to help our people out in their time of need. My proposal is to create a system in which gases prices would fluctuate according to when demand is there. This is to say when more gases is being bought, ie. around rush hour, prices could be raised. This increase in revenue could then be used to lower prices when demand is not as high. This system would then allow individuals that are motivated to save some money to go and get gas when it is cheaper. It would also all those who simply want to get gas and are not as concerned about the costs to go and get their gas when it is convenient to them. This the same pricing scheme used by many gas stations today. Those that are more convenient charge more then those who are not as convenient. Of course some research and definitely some planning would need to be done to implement this most likely it would need to be run at the state, county or city level in order to truly reflect the structure of that given society.
