Price floors must be set above the current and expected market price, if they are not, they become redundant.
Price floors reduce consumption.
The government in the U.K understands that:
Minimum alcohol prices will reduce the alcohol consumed.
But does not seem to want to understand:
Minimum wages will reduce the amount of workers employed.
Someone who is pro minimum alcohol prices and pro jobs, to be consistent, must be against minimum wages as the same logic applies to both policies. Government doesn't seem to get this so what's really going on?

However, there is indeed widespread support for this idea that government should set the price of labour. This shows a basic failure to grasp basic reasoning (the real foundation of economics is logical reasoning – not “studies” whether pro or anti minimum wage edict) – the idea that one can raise wages by passing an edict, is as insane the idea that one can reduce the price of bread by passing an edict. Sadly statists (kings as well as mobs) have believed this for thousands of years.
