To go to the other extreme, raising (or lowering) wages one penny/hr won't change hiring or consumption. The question is, at what point is a MW counterproductive. So far, there's no clear answer.
Imagine there is big swimming pool. There are people and cats and dogs jumping in and out. There is wind. There is the gravitational pull of the moon. There is thermal expansion of the water as the day heats. The water level is up and down because of all these factors.
Someone throws a brick in the pool. Does the brick make the water level go up?
Yes.
Does anyone notice it went up? No. Can I measure that it went up with all that background noise? No.
Did it go up? Yes.
Raising the minimum wage 1 cent is like throwing a brick in a pool. It won't effect things much. It won't be noticeable for the other noise. But it will have
some effect, and the effect will be in the direction of lower demand.
BTW, years ago when I worked for a company in the retail gasoline business the assumption was being 1 cent off the market for a gallon of gas would result in a 5-10% drop in sales.
Fortunately you guys weren't there with your convincing arguments that price had no effect on demand or gas prices might have been a lot higher.
