Technically speaking, this is true. However, it creates the impression that “capitalists” and “workers” are distinct classes with very little intersection. That is not exactly true, to say the least.
Take the light bulb in the picture, for example. Was Edison a worker, or a capitalist? He did part of the work to invent the light bulb. He was also a manager with a team of employees reporting to him, and a business owner. In other words, a capitalist. The same is true for a lot of businesses today.
