No, that's not true. There are plenty of stable market capitalization, dividend-generating public companies. Their cap-to-EBITDA ratio is much smaller, but that doesn't change the fact.

Of course everybody expects the company to take advantage of opportunities - but it has to make economical sense. Nobody wants their company to try to grow so hard the whole company crashes.

Of course it doesn't expect infinite growth. Companies _aim_ for it, but nobody expects them to do it.
