For the last 25 years it's pretty much always taken a recession to cause the Seattle area restaurant industry to lose jobs. Until the new minimum wage increases went into effect this year:
Now, I'm almost loathe to point this (this ^) out because the most common misunderstanding about minimum wage laws is the belief that unless unemployment rose there was no harm. Now, in this case (again, this ^) we do see a harm in job losses, BUT it is not necessary to see job losses to know a minimum wage is harmful. We can also see fewer jobs created than otherwise were going to be created (or slower job growth than would have occurred under a lower wage floor).
I mention this because the most common argument in favor of raising a minimum wage is "it won't cause unemployment." Every $15/hour wage advocate made that argument, and they can all direct their eyes upward to (again, this ^). However, if we toss a ball in the air we haven't disproved the Law of Gravity as the ball is rising. We know it is rising less than it otherwise would have risen due to the Law of Gravity. Likewise with minimum wages & unemployment in instances where a higher minimum wage is accompanied by lower unemployment (like the rising ball) that example does not disprove the Law of Demand because we know employment is rising less than it otherwise would due to the Law of Demand as it relates to the minimum wage.
