Me, you and one other person are neighbors. I grow apples. You and the other neighbor buy apples from me for 1 dollar, and this is a balance which satisfies you, me, and the neighbor.
Now the neighbor has access to a printing press, which allows him to out-bid you for the apples. He comes to me and offers me 2 dollars/apple. I naturally agree, because, being a poor farmer, I want to make as much from my apples as I can to supplement my income and hopefully expand my operation.
Now the neighbor has an obvious edge over you, because he has money that he didn't have to work for (and money in a real, just society is nothing more than transferable labor). He has effectively "bid up" the price of apples from 1 dollar to 2 dollars, and has forced you to expend more labor to maintain your standard of living. I am only slightly less well off, because I'm able to profit from his inflation, but my expenses necessarily go up as his inflationary dollars hit the economy.
The big winner? The counterfeiter. Second place? Me. Loser? YOU.
