So, they’re basically asking for total wage equality, that every worker be paid an identical amount of money per hour of labor. What are the most effective ways to attack such a view of how the world “should” be?
First, this is nothing but a restatement of the labor theory of value. The simplest way to debunk any hard reading of the labor theory of value is by simple example. For instance, you could look at some useful good… say graphite. There are many ways for a person to make graphite. But what they are saying is that the person making graphite from wood ashes should receive the same wage as someone who makes graphite by crushing and burning diamonds. Pick any good, and you can make the same argument.
Naturally, they respond that no one should make graphite by crushing and burning diamonds, but that leads to the next point: who will determine, and how will they determine, the “best” way to make any given good? Ask what is the “best” way to make any good, and then note that the “best” way is determined, in part, by the available capital goods for the procedure. It is impossible to use “best” process X to make good Y unless capital goods A, B, and C are available.
In the past, capital goods A, B, and C were absent, so the “best” method was different. Of course, there is nothing special about the past. The possibility that there is some heretofore unknown set of capital goods D, E and F that permit an even “better” method to make Y in the future is very high. But in order to make D, E, and F, people will need to stop making A, B, C, and Y in order to think up, design, and produce D, E, and F. What incentive is there to do this if there is nothing to be gained by working on D, E, and F?
Is “thinking up new capital goods” going to be a valid job in this society they want to build? If not, who will do the inventing? If so, how do I distinguish a person who is thinking up new capital goods from someone who is twiddling his thumbs? Who will determine what sets of actions will constitute a “job” worthy of a “wage” and how will this information be archived and handled?
That’s a fairly linear argument you can make against wage equality. There are even some side threads you can take. For instance, who determines that everyone is getting paid the same amount? Who observes that no “under the table” production is happening? What happens when someone is willing to work longer (shorter) hours than everyone else? Obviously, the infrastructure for observing and enforcing this wage equality have a nonzero cost. Do these costs come out of the “world bank” first, and then everyone else gets a cut of what’s left?
Of course, no matter how much is spent on surveillance and enforcement, there will always be some chicanery. What prevents the amount set aside for surveillance and enforcement from growing without bound and consuming the entire wealth aggregation? What prevents the people in charge of surveillance from using the information they get from the surveillance from profiting via underhanded methods, like graft or blackmail? (Here I say blackmail because it is the use of information gleaned against the victim’s will which is being used, though I am aware that blackmail is legitimate in a free society)
Basically, through these arguments, you can show that the end result of any attempt to totally equalize wages is a totally authoritarian society, in which the individual has no freedom, but must act on the dictates of some outside force. Whether this outside force is an all-seeing magic computer that has their best interests in mind or a ruthless and evil dictator or group of dictators with their own interests in mind is not something that the individual in such a society can determine. He can be told that everything is for the best by the dictators just as easily as by the computer. The figures of how much wealth is being produced can be falsified, and there’s no way to prove such falsification is not occurring except by each individual going around and seeing everything with his own eyes, which is simply impossible.
There are other ways to debunk the nonsense being spewed, but that’s the one I chose to develop first. Hope this helps.
