> For example, spend the day digging a hole in your backyard. Did you create any value? Nope.
I didn't say that all labor produces value; I said that all value is produced by labor. As a Smart Guy who Created His Own Software Company with No Capital At All, I'm sure you know enough about elementary logic to recognize the difference.
