Services do not add value, they do not create wealth.
and information is value adding.
Information does not add value.
It may however, facilitate value-adding activities to be utilized more effectively.
It may also facilitate services to be performed more efficiently.
But it does not add value in and of itself.
What is value? What is wealth? The answer is simple. You are wealthy when you have something that others want. By distributing and disseminating knoweldge you can create value. Manufactured are just as subject to the laws of supply and demand as intellectual property, and have no more intrinsic value, though their value may be less volatile.
