ok...so you're a costco believer. a wholeseller all the way. what you fail to realize is, that the "middleman" exists in all forms of government, even socialism. it is impossible for every buyer to connect directly with every seller. thus, the middleman is born. if the middle man makes no profit, why bother? some sellers simply cannot or do not want to ship to certain locations, again, the middleman is necessary. take out the middleman and you have a very small economy, perhaps 5000 people or less. you really should read up on economics and the history of economics.
take someone on an outer pacific island who needs something from another island. they can't afford to go to the island to buy the product, because the transportation costs would be prohibitive. enter the "middleman" who engages in transport and so goes to the other island, buys wholesale, and then for his costs, charges you, the consumer, less money for the product than if you picked it up yourself, because he was able to purchase the product in bulk or simply because he had other business there.
your ideas seem to not take into account basic notions of trade. you seem to believe that if someone makes a product 5000 miles away, that the product should cost the same to someone located one mile away.
