Consider two propositions. Firstly, that a minimum price on a unit of alcohol will reduce alcohol consumption by making cheap booze less affordable. Secondly, that minimum wage laws increase the price of a unit of labour, but do not lead to greater unemployment.
These two statements are logically inconsistent and yet many people are able to hold both simultaneously. Some people take the opposite view: that minimum pricing won’t work, but that the minimum wage destroys jobs. They, too, seem to believe that employers respond differently to higher costs than drinkers.
