Stockholders are the heroes of business. Every day, we read the Wall Street Journal, not the Main Street Journal. We hear on the radio the movement of the Dow Jones Industrial Average, not the Dow Jones Wage Average. Wages are kept secret. Profits for shareholders are to be as high as possible.
Employees are outsiders, who are disenfranchised.
The stock market works like a used car market. When you buy a 1997 Ford, the money doesn't go to Ford but to the previous owner. Ford gets the buyer's money only when it sells a new car. Similarly, corporations get stockholder money only when they sell new stock, which mature companies rarely do. But since they're owners, it's fine that they extract corporate wealth forever.
