It seems to me that money was designed as an exchange system where the value of someone's goods or labor could be exchanged for other goods or labor, but that value isn't as important as the modern value. I think when we hear the word economy, most of us think money rather than industry, food, and labor.
My question is, wouldn't there be a certain point at which a profit would draw value directly from the economy, over the possible value of the item being sold, and even be harmful to the economy? I suppose the most obvious exampe would be when a shoe company can make a shoe for less than $10 and sell it for over $100, but I'm thinking in terms of all goods and services. Could and should profit caps be set in some economies? It seems to me like this could be a major cause of inflation.
