This piece illustrates how the products that working people create are used against them under the system of capitalism. However, this practice is also ultimately devastating for society. (As you can see, contradictions abound under capitalism.) But then who among capitalists care about society? After all, "there's no such thing as society, there are only individuals and families." Of course, as sociopaths they are concerned only about their individuals and families.
Under this system labor is seen only as a cost which takes away profits. Hence, the perpetual drive to drive down costs by using machines, crushing or co-opting unions, and finding cheaper labor elsewhere. With more workers unemployed, who can afford to buy their products? You don't need a university education to see where this leads.
An economy under this system is not really designed to meet human needs, but to create wealth for a few. And it has succeeded brilliantly! But for the 99% + of the world's population, it is a disaster.
