Here's the thing about corporations: they're clearly artificial, but legally they're people. They have goals, and operate in pursuit of these goals. And they have a natural life cycle. In the 1950s, a typical US corporation on the S&P 500 index had a lifespan of 60 years, but today it's down to less than 20 years.

Corporations are cannibals; they consume one another. They are also hive superorganisms, like bees or ants. For their first century and a half they relied entirely on human employees for their internal operation, although they are automating their business processes increasingly rapidly this century. Each human is only retained so long as they can perform their assigned tasks, and can be replaced with another human, much as the cells in our own bodies are functionally interchangeable (and a group of cells can, in extremis, often be replaced by a prosthesis). To some extent corporations can be trained to service the personal desires of their chief executives, but even CEOs can be dispensed with if their activities damage the corporation, as Harvey Weinstein found out a couple of months ago.

Finally, our legal environment today has been tailored for the convenience of corporate persons, rather than human persons, to the point where our governments now mimic corporations in many of their internal structures.
