No, this simply isn't true. If it was, oligarchies would never become established.
Failing a strong leader that can create monopolistic conditions in a market, oligarchies are the norm. The reason for this is that the status quo is often more desirable than the risk required in advancing your position.
What you are suggesting will only happen if for some reason, competitors view themselves as enemies. The reality is that it is often the opposite, and nobody wants to rock the boat - except for the upstart.
It's for that reason that new competitors are almost a requirement, never mind a benefit.
