Pretty sure that's what all capitalists strive for, america had a "free market" at one point, monopolization occurred, etc.. The free market competition mythology gives me a laugh.
SD makes good points. Competition is the engine of efficiency in the US economy. Its does force companies to innovate. And encouraging competition is good for the economy in my opinion. The problem is that lassie faire capitalism involves lots of anti-competitive practices because of the elephant in the livingroom:
Business hates competition. They loath it. It cuts into their profits. They do everything they can to eliminate it. And this is nothing new.
People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices.
Adam Smith
From vertical integration to the rail road attempt at new 'net neutrality rules' to to price fixing to wage fixing to purchasing potential rivals to patent trolling to marketing instead of innovating.....business in a lassie faire capitalist system trends toward regional monopolies. Or at the very least, a stark reduction in competition locally. With a full socialist system trending toward a stark reduction in competition due to government monopolies.
The 'sweet spot' is regulated capitalism. Where the natural tendancy against competition that businesses exert is mitigated. And the greatest degree of competition is facilitated.
