You mean growth dependence. When you are forced to grow every year and you can't grow by getting new customers you must steal existing customers from other companies by acquiring them.
'growth dependence' is just a symptom of greed, which is also the root driver of over-consolidation/corruption in markets. that's why a thoughtful regulatory stance is essential to high-functioning markets (e.g., anti-trust, not price controls), rather than the slapdash shit we have now, where parts of markets are highly over-regulated to ensure regulatory capture, while other parts are highly under-regulated to externalize risk.
