My word, you mean competition actually works?

Well, would you look at that! Apparently competition works to the benefit of consumers! Who could have possibly predicted that outcome?

Shop prices fell at the steepest rate for at least eight years last month as the popularity of discount stores among the middle classes helped to drive down the cost of clothing and consumer goods.

The overall price of items at the till fell by 1.8 per cent compared with June last year, with the price of clothes down by 13.7 per cent year-on-year.

The figures, compiled by the British Retail Consortium/Nielsen shop price index, show the fastest drop in prices since the trade association began compiling data in 2006.

It was also the 14th month in a row in which shop prices fell, easing the pressure on households where wage-earners have suffered pay freezes.

Yes, of course, the capitalists are straining every sinew to increase the profits that they make from our need for basic necessities such as food and drink. But in doing so they find themselves competing with other capitalists who would also like to like that pelf from our pockets. That competition then limiting the amount any one shop can charge and finally leading to falling prices for consumers.

Of course, a number of people have pointed this out before, starting with Adam Smith, Bastiat had things to say on the point and even Karl Marx got it. Monopoly capitalism is to be avoided for it is without that competition, for it is that market choice that makes such a system work to the benefit of consumers.

This is all obvious to us, the initiates, of course. But we need to continue to make a song and dance about it. Yes, there really are things that governments must do that cannot be done by other actors. Yes, there really are times that said government must intervene in the economy. But for the most part that intervention necessary is simply to ensure that competition is possible.

It's not necessary to ensure that competition is happening, only that it can. For a monopolist in possession of a contestable monopoly is unable to exploit that monopoly for fear of competition arising to contest it. It's not even necessary to have a level or even playing field, only to have an open one.

Worth noting the next time someone starts to complain about the monopoly of the supermarkets (as they do every few years, prompting yet another enquiry). Precisely because competition is forcing prices down we've obviously not got an exploitable monopoly here.
