Regardless of what you believe, it's not part of the definition, so it shouldn't be phrased as such.  Now, apparently, you want me to teach you economics.  Fine.  Payment of wages for labor is an emergent phenomenon.  In free markets, a number of things happen.  Technology advances, which increases the return to sepcialization.  Interest rates and average profit margins decline.  Both of these make it harder for one person to have all the skills to competitively run all parts of the business.  So, people start to sell just the input they're (comparatively) best at. That gives people a much higher return for their efforts than investing money at 5% interest, or trying to do all functions of the production process well. But we really shouldn't be using the talk page for economics lessons.
