I think it’s disingenuous to keep pushing this idea that corporations cannot survive without ever increasing income.
What would happen if your employer said you would never again get a raise? Most people would probably start looking for another job. At a minimum, they expect their long-term income to keep with inflation.
But if employee salaries are expected to grow over time, then so are the company revenues that pay those salaries. A company whose revenues stop growing is like an employee whose salary stops growing. They will not last long at whatever they are doing.
