This is actually a fairly important question as Amazon is obviously a corporate trust. These aren't actually supposed to exist, we decided long ago as a society that, structurally, these sorts of entities are more likely to harm and exploit a society than to serve it. Any of these impossibly-large corporate entities could turn on a dime and be an apocalyptic economic storm of evil and enslavement. 

Personally, I would rather place my faith in a corporate-busting FTC that goes out there with enormous zeal to keep entities that threaten our freedom broken up and dispersed to harmlessness. This is actually becoming more important, not less, as time marches forward, and yet, we've allowed our government's essential vigilance to falter with entities like Verizon, Microsoft, ALCOA, Monsanto, Comcast, CenturyLink, WalMart, just about every energy industry player, and, of course, the old grandaddy of evil fascism itself, the military-industrial complex.
