Protecting competition, not competitors. The difference may be subtle, but real nonetheless. The DoJ may be reacting to a complaint from Amazon, but they are not "defending" Amazon, they are going after violations of antitrust laws. Cartels have been illegal under U.S. law since 1890. I have to shake my head in wonder over how this could become controversial, more than 120 years after the fact. I mean, we figured out a long, long time ago that it's bad for our economic well-being to allow companies to band together and fix prices for goods. Even old Adam Smith recognized this as a flaw in free markets. So I don't know what reading of even the most classical economics supports a philosophical argument against antitrust law.
If Amazon uses their market power to restrain trade, have no fear that their competitors will beg the DoJ to bring a complaint against them. The fact that they have a large share of this market is not in itself actionable. It's what they do with that market share that matters.
I have to shake my head that, more than 120 years after the fact, the many failures of anti-trust laws are still ignored.
The same people who shout, "anti-competition!" when private firms form loose associations to "set prices" can also be counted on to screech, "predation!" when a rogue firm (e.g., Wal-mart) "dumps" by setting prices lower than their competitors are willing to go.
So, what will satisfy you?
You don't want multiple firms cooperating to set prices, but you also don't want a single firm undercutting the prices of its competitors. Well, you can't have your cake and eat it too, so what's the solution? Enlisting bureaucrats to decide the prices at which producers may sell and the prices at which consumers may buy?
Central planning doesn't work because the untold *billions* of variables affecting market conditions make it impossible for a committee of finite-minded bureaucrats to determine an "optimal" price or competitive environment. Attempts at doing so inevitably distort the market, ultimately causing economic harm to producers and consumers as a result.
There's a better way: let the market determine prices.
And it's easy -- leave firms free to charge what they will for their goods and services, even if they use said freedom to form loose associations (i.e., "collude"), and allow consumers to decide what they are willing to pay.
Demands for anti-trust regulation also tend to be emotive: collusion is simply a pejorative for cooperation. Many of those who cheer on anti-trust law suits are perfectly fine when unions collude to set prices -- a much bigger problem, by the way, than any collusion in the eBook market.
The truth is, cartels can't endure long enough to do any long-term harm for the following reasons:
- If pooling resources is more profitable than going it alone, the cartel members will merge.
- If pooling resources is less profitable than going it alone, the cartel will dissolve
- An outsider will enter the market with a better product/business model and out-compete the cartel (Sam Walton vs. Sears Roebuck)
So, the harm inflicted by cartels ultimately null. Unfortunately, the same can't be said for anti-trust laws. Cartels are temporary, government regulations are forever.
