Joe...I never said anything about 'equality" in matters of compensation....I merely stated labor adds value to the finished product and should be compensated accordingly...
How do you determine appropriate compensation?
If I start a business making chairs and I'm paying $10 for the wood, glue, etc. per chair, it takes an hour of labor to make a chair and they sell for $100 each, how much should the guys making them be paid? Theoretically the labor is adding $90 of value, but obviously if the guys are paid $90/hr that doesn't leave anything for overhead for the factory, management, sales, etc.
Let's think about two potential scenarios. In one, I've got a big mortgage on the factory, do a lot of TV ads, and have a showroom for customers to come and buy them. In the other case the factory has been paid off years ago and the reputation of the company is so good that no advertising or sales staff is needed because the customers just show up at the factory to buy the chairs (don't laugh, it works just like that for the Amish who sell furniture about 20 minutes from here)
Let's say in the first case the breakeven occurs when paying the workers $15/hr, any more than that and I'm losing money. In the other case the breakeven is $75/hr due to the almost nonexistent overhead.
If $15/hr was considered fair wages for this work in this area (because that's what all the other chair makers paid) then it would be hard to argue that I should pay anything other than $15/hr in the first case. But in the second case, do you think I owe it to the workers to pay them more, because if I paid them only $15/hr I'd be making $60 on every chair they made? Do I deserve all of that $60, only part of it, or none of it?
Think about it a bit, because the reason I have no overhead is because I paid off the factory building long ago -- I could take a mortgage out on it and use that money for something else that might be profitable to me. The reason I don't have any selling expenses is because of years in business doing right by the customer have given my company such a great reputation that the chairs sell themselves. Put another way, how much of that profit do I deserve for my terrific business skills versus how much the workers deserve for doing such a great job producing quality product that everyone wants to buy?
