LET’S start with a recap on “surplus value.” Before Marx, economists recognised the key importance of work — a distinctive feature of our species — to the creation of everything that humans need to survive.
What Marx added is the recognition that under capitalism, in “selling” labour power (their capacity to work) to any employer, workers receive less than the value they produce.
The difference — “surplus value” — is taken by the owners of capital, some of which is invested in more capital (“capital accumulation”) enabling them to extract more surplus value; for the capitalist, this is a virtuous cycle, underlying the extraordinary dynamism of capitalism.
