Mergers ruin everything
In an unregulated capitalist economy, the inevitable end result is monopoly. The best way to compete in the economy is to not have to compete.Without external restraints, any sufficiently large company will focus on eliminating competition either through pricing them out of the market or just outright buying them.The only reason the US has more than one cellular network right now it because the government has prevented multiple attempts at mergers, and even with that effort we're down to three.edit: if you disagree, I'd love to hear your opinion. The government has entire agencies dedicated to maintaining competition in the economy. If monopoly was not the inevitable end result of capitalism, then such agencies would not be required.
