The bosses like to call it “free enterprise.” But for the millions who do the work — who keep society running and still can’t keep up with the rent, the bills and the price of everything — the system is neither free nor enterprising. What makes capitalism tick, and why does it so often bring war and economic catastrophe?

Capitalism is a society divided into classes, where a few fabulously rich parasites are supported by the sweat and labor of a vast number of working and oppressed people.

Wage slavery hides the robbery

In every class society, it is human labor that has sustained society and created its wealth. What sets capitalism apart is the form its exploitation takes. Its typical worker is legally “free”: owning nothing but the ability to work, and forced to sell that ability — labor power — to the owners of capital (the capitalists, the bosses, the bourgeoisie) simply to live. Unlike the open bondage of the slave or the serf, this bondage is concealed. The worker looks free and looks fully paid, while the unpaid labor that becomes the capitalist’s profit stays hidden inside the wage. This is wage slavery.

The boss buys the worker’s labor power for wages but always pays less than the value the worker adds. That difference is surplus value, the source of the capitalist’s profit.

Capitalism rose on slavery

But capitalism did not rise after slavery and leave it behind. It rose on slavery. The plantations that worked millions of enslaved Africans were modern enterprises, and their cotton and sugar built the fortunes and fed the factories of the rising bourgeoisie. Some of the largest workplaces in the world then were the slave plantations — a Caribbean sugar estate might drive 200 enslaved people or more, larger than the average English cotton mill of the day. “Without slavery you have no cotton,” Marx wrote in 1847; “without cotton you have no modern industry.” The enslaved belonged to the modern working class — and were among the first anywhere to turn the mass strike into a weapon, from the plantations to the revolution in Haiti.

Marx named it: expropriation, open robbery

Marx had a name for this founding robbery. The economists called it “original accumulation,” as if the first great fortunes had been saved up by men more frugal than the rest. Marx tore up that fairy tale and named it for what it was: original expropriation — open robbery. The seizure of the common lands, the conquest of the Americas, the plunder of India, the trade in enslaved Africans: these, he wrote, were its “chief moments.” Expropriation is robbery in broad daylight; exploitation, the daily taking of surplus value, is robbery hidden inside the wage. And expropriation did not end once capitalism stood on its own feet — capital still tears people from the land and the means of life wherever it can.

Production becomes social, ownership stays private

Capitalism has been dynamic in developing the means of production. Under feudalism, the land owned by the lord or king produced mainly what the nobleman and his court could consume, with a bare subsistence going to the peasants. Capitalist production is mainly for exchange — which means finding markets to sell what is produced. Competition for those markets drives every capitalist to increase production and make it more efficient, most often at the direct expense of the workers, who are exploited at an intensity unknown under earlier systems.

The drive for a competitive edge has led to a greater and greater concentration of production under giant enterprises. Corporations arise that employ thousands of workers and control every step in the making of a good, from extracting the raw materials to delivering the finished product. In this way production becomes more and more socialized — and the development of capitalism produces the very force that must overthrow it: the working class, the proletariat, thousands now brought together to labor cooperatively, often under one roof.

But this social character of work and production is completely at odds with the private ownership of production. A constant struggle goes on between workers and bosses over the division of surplus value, the workers trying to raise their standard of living, the bosses to maximize their profits.

Overproduction: too much to sell, not too much to use

Capitalism also breaks down from within. Because each owner produces for profit, with no plan for society as a whole, more goods pile up than can be sold at a profit. This is what Marxists call overproduction — not too much for people to use, but too much to sell. When it hits, the factories close and workers are thrown into the street, not because too little has been produced but because too much has. The warehouses stay full while the people who filled them go without. It is poverty in the midst of plenty, and it returns with every slump.

The system is inefficient and drives toward war

Capitalist efficiency, too, exists only within each corporate enterprise. Taken as a whole, the system is horribly inefficient, with millions of worker-hours poured into parasitic industries like armaments and advertising. Arms production is not a waste the system could simply cut away; it is driven by the rivalry among the big capitalist powers for markets and domination. There is duplication and waste from secrecy and competition — patents, for example, and 40 different brands of toothpaste.

As the world economy grows more complex, it becomes ever clearer that humanity must plan production to use raw materials wisely and keep the earth habitable. But overall planning is impossible under capitalism: production is geared to profit, and every other consideration is sacrificed to that motive. And capitalist rivalries and the need for markets lead inevitably to war — the greatest destroyer and polluter of all, threatening the very foundations of life on this planet.
