Utopia from Gulliver's Travels...?

You are correct that you have no idea how economics work. No offense intended. Economics involves the reality that resources are scarce -- that nothing is unlimited supply and to get more of one thing you have to give up some of another. The definition of Utopia is: An impractical, idealistic scheme for social and political reform. In other words, something that sounds lovely, but can't really be accomplished -- in this case because you've assumed away the reality of scarcity.
