Editorial: Given the law of supply and demand, maximum total utility is assured only in a pure free market economy, although other types of economies might be able to achieve it. Obviously, then, a country that has a highly controlled economy, and is not trying to bring about a pure free market economy, is not acting in the way that is most likely to bring about maximum total utility. The editorial's argument is most vulnerable to criticism on the grounds that it ['presumes, without providing justification, that any country that does not have a pure free market economy has a highly controlled economy', 'presumes, without providing justification, that the way in which utility is distributed is less important than the total amount of utility', 'fails to consider that the way most likely to achieve a particular end may not be the only way to achieve that end', 'presumes, without providing justification, that trying to bring about a condition that will ensure the achievement of an end must always be the way most likely to achieve that end']
