Well that’s just basic common sense. At my job we have a wide variety of pay scales depending on what department you’re in. Whenever we have a blizzard they ask anyone with a CDL if they want to help plow snow. The catch? You make your pay rate. How many volunteers do you think they get at 15 dollars an hour when most of the plow truck drivers are getting 50? I reversed it, but it’s the same concept.
Basic common sense is what BiggestAl is missing. Hence he thinks if you raise the minimum wage, it somehow magically improves everything. 
So does the poverty level also magically go up? Asking for a friend.
No magic involved.
