The problem is that, in a world of floating exchange rates, as Italy was before the euro, if one country is subjected to a shock which requires it to cut wages, it cannot do so with a modern kind of control and regulation system. It is much easier to do it by letting the exchange rate change. Only one price has to change, instead of many.
Milton FriedmanFor example, the supporters of tariffs treat it as self-evident that the creation of jobs is a desirable end, in and of itself, regardless of what the persons employed do. That is clearly wrong. If all we want are jobs, we can create any number--for example, have people dig holes and then fill them up again, or perform other useless tasks. Work is sometimes its own reward. Mostly, however, it is the price we pay to get the things we want. Our real objective is not just jobs but productive jobs--jobs that will mean more goods and services to consume.
Milton Friedman...Only physicians are likely to be regarded as competent to judge the qualifications of potential physicians, so licensing boards in the various states...are typically composed..of physicians,...members of the AMA. The boards, or the state legislatures...give the AMA the power to influence the number of persons admitted to practice (by) lengthy training,...(and) the list of 'approved' schools and hospitals (which) is generally identical with the list issued by the Council on Medical Education and Hospitals of the AMA.
