The rest is a complete mess written by someone who is uninformed at best. The discussion of tobacco taxes and the discussion of wages in the Premier League are both particularly bad. Please don't take it seriously as a description of what's going on in the field or what the current problems are.
When I teach my freshman undergrads supply and demand in two weeks I will make very clear to them that we do not have that much empirical support for the claim that minimum wages increase unemployment and that it is an unsettled question. This is the first college-level economics class they will take in our department and I am going to make sure they understand that point. I would be willing to bet that nearly every one of my colleagues teaching similar classes throughout the US and abroad will do the same when they discuss minimum wage policies.
