The invisible strangling hand of the market.

It seems that the Ayn Rand scholars may have some rethinking to do. Story here New Zild has a supermarket market that is a duopoly and thus prices are not in competition with each other thus we pay more for groceries than everybody else outside of the International Space Station.

An associate professor from the university's School of Business, Frank Zumbo, says Australia and New Zealand both have supermarket duopolies that act as "cosy clubs" and that's the reason for the high prices.
Professor Zumbo told Checkpoint it's a fundamental economic principle that more independent competition leads to lower food prices.

Firstly Prof. Zumbo is the best sounding name of an academic this year, no question. Then he points out what has happened, the market was a glorious free-for-all and prices were cut to gain market share. For a while. Then two players took over and now...supermarkets sell watercrackers singly.
But this is not what we are told; Companies will prosper and expand whilst the market is there for us to benefit from, they won't merge, become huge and pretend that they are still a free market. That would defy the teachings of Chicagoans and Randians.
And that would be just awful!
