Businesses do not always need to grow at all, neither do investors as a class, demand that business keeps growing. A mature business generates a stream of dividends and everyone is happy. There are many, many such businesses.

One famous example is See's Candy, which Warren Buffet famously discussed in one of his newsletters. See's is a mature company with zero mandate to grow. It turns the profits over to Berkshire and Berkshire uses that to invest in other companies.

The economy as a whole keeps growing because human desires and ingenuity are unlimited. But a specific firm reaches its natural limit, at which point it turns into a cashflow machine to generate dividends for owners.

The problem you are facing is that Management does not want to acknowledge that it's time for them to start paying out dividends and leave growth alone, because that would be an admission that the profits of the firm are best invested by some other firm, and not by them.

It is all about management ego, in not recognizing their limitations, and then destroying the core company as they invest in areas where they can't compete. Shareholders and boards need to replace management when this happens, but it is hard to do because Management keeps insisting that they can earn an above average return if they keep the money rather than returning it to shareholders. And people love to hear stories of above average returns.
