Really, I'm surprised by Dilbert. His point is what most drives pricing in most markets: the reality that it's better to *not* aggressively compete, because your competition will fight back, and it's better to respect the 'natural equilibrium' of the market - i.e. to wink at your competition and say "I won't charge less if you don't".
But it's an awfully mercenary philosophy, highly unethical, and sometimes even borderline illegal. It's the kind of thing that Dogbert would promote.
Is better for big companies to form cartels and then pretend to be competing between themselves. Then, with the new cartel, they can buy up government and place regulation that will smash smaller companies to the ground.
