So I want to get the fruit moving to market first. If they take the same amount of resources and labor and I have a preference, it proves that labor is not all there is to value.
OK so is that the end of the story? No because why did that wheel have utility? Its because it was broken. It was an economic shock. What it represents is a distortion from a planing perspective. From a planing perspective I want marginal utility to be low. I want two wheels, not one. A third wheel would be a buffer stock with no marginal utility. Does that mean that having a spare wheel is of less value than being short one wheel? Does it mean that 3 wheels are worthless? What if there were wheels everywhere? It would mean wheels are worthless. Then, no one would put labor into them. That is when it meets labor. Labor is going to be quite reactive and thus very much related to economic planning.
* Labor theory pertains to economic planning.
* Marginal utility applies to economic shocks
A perfectly planned economy without restrictions will tend to be priced into the time taken to produce them. 3 people who want an apple and 3 apples does not extract economic rents. 1 apple and 3 people who want an apple does but that is a supply shock and a macro economic plan that failed. Certainly there is skill involved and producers can plan poorly.
The other point of view on this is that labor theory applies to how humans can affect value. The idea is not to make things valuable, but to add value. Something cannot have utility until it exists. The only variable we have control over is human labor. So you want a plan to motivate more labor. There is no direct means to modify the economic shock that raises marginal utility. All we can do is to throw labor at it.
However one additional complaint I have is that those who misapply marginal utility is this idea there is no free lunch. Since the determined value is clearly not related to the amount of labor put into it, by definition, value can increase with no work. How can there be no free lunch with marginal utility?
Maybe its easier to say labor has marginal utility as well and the best way to direct it to where its needed is paying them accordingly. At some point time will increase their marginal costs linking time spent with value.
On both extremes it reaches absurdity since giving a knife to someone is suicidal can hardly be seen as valuable and likewise the time it took to build a bridge that falls into the river hardly defines its value. They are both worthless.
