It's another example of predatory capitalism - a rogue model of capitalism that emphasizes maximum short-term profits for corporations and shareholders, and a complete disregard for social responsibilities, environmental protections, or the well-being (or for that matter, the very lives) of anyone who is not an owner or shareholder.
For roughly 30 years following WWII, corporate profits and personal income grew steadily, at roughly the same rate. Seen on a graph, the two lines are almost perfecty parallel. As the American worker produced more wealth for their employers, they earned proportionately more.
Beginning in the early 70s, personal income began to flatten out, and in real terms, has remained essentially flat for 50 years. Corporate profits have continued to climb sharply, rising over 300%. In other words, the people doing the work have produced 3 times as much product or service, and are still being paid what they were paid in the mid-70s.
This is just greed; corporations are squeezing every single penny they possibly can out of every single source they can find or create, for no other reason that they can and they want to. This is the primary driver of inflation; more than half of inflation is larger profits being taken by the corporations.
America was much healthier, and a better place to live by far, when corporations recognized that a healthy society was one where everyone did better when everyone was doing better. Corporations used to recognize that a stronger, educated, healthier labor pool was good for business. Henry Ford himself, who despised labor unions, knew that it was simply a smart business decision to build a car that the people who made it could afford to buy without going broke. Just try finding a corporation today who operates that way.
