There may be some truth to this, but I think it's more about American front line workers making a living wage. I know for me, I get my blinders on and I expect that when I go to the Dollar General, or the Quick Trip, etc., I want to be checked out in a timely fashion. I expect those workers to do their job and "serve my needs" quickly. I often do not think about the fact that a two income household could be forced, by today's wages, to live on $600/week ($300 each). A raise in minimum wage would be life changing for those households. They could come closer to living on $600/week each ($31,200 per year).
I do not and will not claim to be well off or above middle class, but I know I would not be able to live like I want to or like I do on $31,200/year. Nor should I expect that others would. If that causes my cost of goods go up a little, then do be it. I'm for ALL people to have a chance at a better quality of life.
Just my $.02.
