I'm not sure what you would define as a monopoly, but for me it is a company that is able to charge exuberant prices without fear from competition. It isn't simply market share.antman said:Just one example of a naturally evolving monopoly Standard Oil, grew and and absorbed all competition despite state anti-trust legislation - Rockefeller was able to through shrewd organisation and secret deals between players to consistently beat the system until finally the Sherman Anti-trust legislation forced a breakup of the company and its affiliates.
There was plenty of room for new players in the oil refining and distribution industry but Standard Oil acted aggressively to undercut and then buy out all other players. Their dominant market position allowed them to do this.
Now the typical libertarian response to the Standard Oil case is "yeah sure the thing we said can't happen happened but in fact Standard Oil lowered prices for the consumer so it was all good". That may have been so but it flies in the face of the standard libertarian mantra of "only governments can create monopolies".
The truth is always more complex than a simple "one size fits all" philosophy can account for.
Standard Oil is a bad example if you wish to demonstrate that it was a monopoly. For one thing the industry's output increased rapidly after 1870, which is not something you would expect to see if a monopoly operated. In any case by the time Standard Oil was broken up it only had 11% market share, as Associated Oil and Gas, Texaco, Gulf and dozens of others entered the market. As you pointed out, the cost of oil dropped dramatically, and this is what I'd argue is the reason why the company was so dominant.
We associate monopolies as bad for the economy, yet you use a company that brought cheap light to millions as an example of something that needed to be stopped by government :headscratch
