Every man speculates upon creating a new need in another in order to force him to a new sacrifice, to place him in a new dependence, and to entice him into a new kind of pleasure and thereby into economic ruin. Everyone tries to establish over others an alien power in order to find there the satisfaction of his own egoistic need.
– Karl Marx, Marx’s Concept of Man, 140
It should be noted in the above quote, taken from Marx’s Economic and Philosophic Manuscript of 1844, that Marx indicates that it is “[e]very man” and not just capitalists who have an interest in exploitation. The capitalist is not unique in the desire to exploit others, that is common to us all, says Marx. What separates capitalists from everyone else is that they have the means to exploit. If we are not all free, then none of us are, and this is precisely why.
In this post, I want to give a libertarian socialist defense of universal basic income. This will require some specific definitions to the notion of “universal” and “basic” and it will require a defense that is not reliant on consequences. In other words, to be a libertarian socialist defense, it cannot say “hey, see how this, and this, and this would be better with a UBI!” Such arguments are all well and good and have been made repeatedly by others with better data and research than I care to possess. See here, here, and here for arguments of that kind. Instead, I want to present us with a socialist argument for, what I will call a guaranteed income. The reason for a socialist argument is that without a rupture with capitalism, a universal basic income would really just subsidize wages for employers.
Before I present the argument I need to be clear about what I’m suggesting. The “guaranteed income” is not really universal and “basic” is too abstract to be of any value. What I intend is an income for people whose labor is less traditionally rewarding in a capitalist society, but is nevertheless important. The first and foremost of these types of labor is what I’m calling austerity. Austerity is the labor of making do with less. Austerity is the job of the poor. They learn to live with less so everyone else can have more, more cheaply. This is thrift and it is so often exploited that I don’t think another living soul has ever even suggested that the rich exploit the poverty of the poor. They take the benefit of being poor, which is free time, and remove the ability of the poor to be industrious for their own gain. I will spare us the details but suffice it to say that it takes a lot of work to be poor in a capitalist society, see Nickled and Dimed by Barbara Ehrenreich for why. Other types of labor are better known as labor if still unpaid or underpaid. Domestic labor is at the head of this class, followed shortly by child-rearing and education, and the copious amounts of internships and art gigs people do in the hope of building a portfolio.
Free labor that benefits another is another class like austerity that I’ll be mentioning. This one already has a name. It is called slavery. A guaranteed income, as we will see, conforms slavery into austerity, where one has little but their free time is, in fact, their own. However, it is not necessary to be fair that everyone would receive this income, it is only necessary that everyone could receive this income and merely for being alive. In this sense, it’s not really universally applied despite being guaranteed to all. Everyone is guaranteed some income if they choose to take it and don’t already make more than it offers. But how much should it offer?
I recommend that the price of the income be pegged to some sort of productivity index. There are several to choose from: the Gross Domestic Product, Gross National Happiness, Genuine Progress Indicator, the Happy Planet Index, and more. Whichever index we light on, we’ll want to set a standard level for the guaranteed income, say around a quarter to a third of the per-capita distribution. This would vary, year by year, and have the important fact of driving people back onto the labor market when productivity slacks. It will no doubt find a reasonable equilibrium and the point at which comes to rest will mark the divide between the interest in free time and that of affluence.
That brings me to my argument. We might start by graphing these mutually exclusive human interest: free time and affluence. They represent the twin concerns of political economy: how to maximize non-labor time while also maximizing prosperity. The Marx quote above echos the understanding of the Ancient Greeks and Egyptians before them: if you want to be free and prosperous, then you must have slaves, which, morality aside, makes complete sense. The only way to exist in a state of wealth and ease is to have others produce the wealth without their enjoying it so that you can. Capitalism supposedly offered a way to avoid this economic truth, but it was Karl Marx and his theory of exploitation that pointed out that capitalism only nominally abolishes slavery. Marx showed that what appears to be contracting between free individuals is actually coerced and ultimately exploitative, i.e. wage-slavery. This form of slavery only paints a patena of voluntary decision-making over the forced slavery of explicit slave-society.
This entire system of human interests can then be mapped out for us. (Forgive the crudeness of my graphs.) In figure one below I have place affluence or relative wealth on the vertical axis and the amount of time one would need to spend laboring versus the amount of time one has free on the horizontal axis.

In a capitalist system, the red line represents everyone’s prospects giving the uncheck desire to place all others in a state of laboring for their own benefit and not the benefit of the laborer. You can see near the equilibrium point (0,0) the line is diagonal showing that the more you work, the more you make, the less you work, the more free time you might enjoy, but at some point, and that point is arbitrarily illustrated here, the line bends around in both directions. So that we might extrapolate four classes of individuals in a capitalist society. Those that labor little to none at all we might call the capitalist class, or what Marx called the bourgeoisie, depicted below in blue. Those that work excessively and yet “enjoy” intolerable poverty we call the slave class, depicted in black below. The two in the middle, which could conceivably be seen as one class (under socialism) is characterized by the idea that the more they labor, the more wealth they enjoy or the less they work the more free time they enjoy, these are the laboring class or proletariat and the austere class respectively, depicted in purple and green below.

We can see that there is an artificial arc here against what our morality would tell us; that the more you work the more prosperity you ought to enjoy. We can then divide the graph into four zones along the axes.

Each zone in figure three represents a potential set of individual interests. Here, the capitalist zone is the most desirable since it works the least and enjoys the highest degree of wealth. However, having a capitalist class necessitates a slave class, and what is more, the capitalist class will always be pushing every other into the slave class. This is similar, but not exactly the same as, what game theorists call a prisoner’s dilemma. Every individual having an interest in being a capitalist will naturally result in the overwhelming number of people existing in the slave class. A constant pressure to rise on the line will force everyone else down the line. But also like the prisoner’s dilemma, a simple solution exists: make a rule. In this case, we must eliminate the ability to make money from another’s effort.
On the one hand, doing this must involve abolishing the form of rent which I have spoken of before. But that is not enough. Even with the mechanisms of the exploitation of labor removed, the mechanism for exploitation of free time would still exist. The result would be a “capitalism of the proletariat”, a new kind of socialist dystopia. This is why we need a guaranteed income, it effectively straightens out the curve so that every individual is left free to choose between the level of free time and the level of affluence they would like to enjoy. If the curves we saw on the line represent exploitation, then their elimination under socialism entails a lack of exploitation.

You’ll note in figure four above, that the red line never enters either the slave or the capitalist zones. This is necessary, should there be a capitalist, there must be slaves. Thus the only way we will all be free is if none of us are allowed to be capitalists. To guarantee an income would be one of two steps necessary to effectively and actually abolish slavery for the first time in recorded human history.
