M-C-M’ is a way to understand how capitalists keep and grow their wealth. It starts with M, which stands for money. A capitalist uses this money to buy C, which means commodities things like raw materials, labor power, or tools needed to produce goods. Then, after producing and selling the new product, the capitalist ends up with M, more money than they started with.

The key point is that M is greater than M, meaning the capitalist doesn’t just get their original money back they make a profit. This profit comes from the value added by workers labor, especially the unpaid part called surplus value. So, capitalists keep their wealth growing because they invest money to produce goods and sell them for even more money. For example, imagine a capitalist has $1,000 (M). They use that money to buy materials and pay workers (C) to produce shoes. After selling the shoes, they make $1,200 (M’). The extra $200 is profit, which came from the workers labor adding value beyond what they were paid. This is how capitalists maintain and increase their wealth.

Concentration of Capital and M–C–M’

In this week’s reading, Michael Parenti explains how wealth in the U.S. is concentrated in the hands of a small capitalist class. These are people and corporations who not only own large amounts of money and property, but also control the means of production factories, businesses, land, media, and more. They maintain and grow their wealth through a constant cycle that was also discussed in Reading 5.1: the formula M–C–M’.

M–C–M’ stands for Money – Commodity – More Money. It shows how capitalists operate in a capitalist economy:

• The capitalist starts with money (M).
• They buy commodities (C), which includes both raw materials and labor power (workers’ ability to work).
• Then they use those commodities to produce goods and sell them for more money (M’) than they started with.

The key part here is the M’, which represents surplus value the extra profit gained from the labor of workers. Workers are paid less than the value they produce, and this difference becomes profit for the capitalist. For example, if a capitalist pays $100 in wages but sells the product for $300, the $200 difference is surplus value that increases their wealth.

This process helps explain how capitalists remain wealthy. They don’t stay rich just by saving money or working hard they invest money to make more money, using workers’ labor as the source of value. As Parenti points out, this cycle allows the top 1% to own more wealth than the bottom half of Americans combined. That’s why wealth inequality keeps growing.

The formula M–C–M’ is the engine of capitalism. It shows how money turns into more money through the exploitation of labor. It also explains why there is always a struggle between workers, who want fair pay, and capitalists, who want to maximize surplus value.

Understanding this cycle helps us see that wealth in the U.S. isn’t just about individual success it’s about a system that rewards ownership and control, not labor.

M-C-M’ stands for Money – Commodity – More Money, and it helps explain how capitalists stay rich. Basically, a capitalist starts with money (M), uses it to buy or make something (C), and then sells that thing to make even more money (M’). The goal isn’t just to break even—it’s to make a profit.

The important part is the M’—the extra money they end up with. That profit mostly comes from workers, because they get paid less than the value they actually produce. So, by repeating this process over and over, capitalists keep growing their wealth. It’s not about meeting people’s needs—it’s about turning money into even more money. That’s how the system works.

1. In capitalist society, wealthy individuals maintain and increase their class status through a process summarized by the formula M–C–M′. This diagram represents how capitalists invest money (M) to buy commodities (C), such as labor power and raw materials, and then sell the finished products for more money (M′). The difference between the initial money (M) and the final return (M′) is called surplus value, often represented as m′. This surplus is the source of profit and is only made possible through the exploitation of labor. Workers are paid less than the value they produce, and the capitalist pockets the difference. Unlike the cycle C–M–C, which describes working-class life, where a person sells a commodity (like their labor) to get money in order to buy another commodity (like food or rent) the M–C–M′ cycle is not about survival or need. It is about expanding capital. Capitalists do not spend money to satisfy personal needs, but to make more money. This makes the cycle continuous and self-reinforcing. As long as profit can be extracted, the capitalist remains wealthy and able to reinvest in more labor and production to generate more profit. This system ensures that wealth is concentrated in the hands of those who already own the means of production, reinforcing inequality over time.

So like M–C–M′ is a way to show how rich people (capitalists) keep staying rich and even get richer. Basically, it means they start with money (M), then they use that money to buy stuff (C), like tools, materials, and they also pay workers. Then they make something and sell it for more money (M′). The new money they get is more than what they started with, and that extra money is profit. But the workers don’t really get paid for all the value they create. Like, they work hard making stuff, but only get paid a small part, and the owner keeps the rest. That’s called surplus value. The whole point for the capitalist is not to buy stuff they need like food but to just keep making more money. That’s why they keep doing this over and over, M to C to M′ again and again. So that’s how they keep their money growing, by using workers and owning the stuff needed to make things. That’s why the rich stay rich and workers kind of stay stuck unless something changes.

Jalee introduces us to the M-C-M concept that capitalists use to keep and maintain their wealth. This keeps them wealthy by not just keeping or saving their money but having their money work for them. Capitalists begin with their money, and then use it to buy commodities. A commodity would be something like a machine or material that will be put to use for profit. An example of commodities would also be labor power, where capitalist buy labor from workers to produce profit as well. At the end of this cycle is money again which is the profit and capitalist end with more money than what they started with. 

Before capitalism, people like farmers and artisans would sell something they made, like vegetables or cloth, to get money, and then use that money to buy something they needed. This was called C-M-C, which means commodity to money to commodity. They were just trying to survive and trade what they had. But when capitalism started, rich people with money didn’t sell to buy—they bought things just to sell them again and make more money. This new cycle is called M-C-M’, which means they use money to buy something and then sell it to get even more money. The extra money they make is called surplus value, which is basically their profit. At first, capitalists just traded stuff, but then they realized they could make more money if they owned the buildings, machines, materials, and paid workers to make the products for them. Then they sell those products for more than what they spent. This keeps going every day as a way to grow their wealth. The big difference is that regular workers are working to survive, while capitalists are investing to make more money off what other people do.

M-C-M’ is the general formula of capital. Money- Commodity – Money’ (Greater). The first M in MCM stands for money and is how much the capitalist started with. C is for commodity, which can be something used or bought by the capitalist. This is also where the laborers come in and use these materials bought to work on something the capitalist owns, using their labor power. The last M’ is also money, but now the value of the money has increased from the first M of the formula. The last M is considered as the gain or profit made, also known as surplus value.

This is how capitalists own so much wealth. They do not work as hard as the laborers they hired, but benefit more from the work being done for them. On page 23 it states, “capitalists would never use their money for the purchase of a commodity that they could not resell for more than they had spent”. This explains the MCM’ formula great as capitalists only use the money they already have started with to create even more of it by purchasing commodities and laborers to create even more money than they have started with. They typically will purchase buildings, machines, equipment, raw material, and labor force to produce something of a higher value than what they originally spent.

The M-C-M’ diagram illustrates how capitalists maintain their money and increase their capital. They start with M (money), which they use to buy C (commodities), which include labor, machinery, and raw materials. This stuff is used by workers to create things that are eventually sold for M’ (more money) than the capitalist initially had. The worker’s labor is the source of the surplus value, or additional money. The capitalist keeps the profit even while the workers do the labor. By investing in labor, rather than working themselves, the wealthy are able to increase their capital over time.
