I think tax breaks and/or compensation for higher ups is a smaller gap to regular employees. WalMart's prices and Target's prices haven't exactly skyrocketed. You can still get 3 dollar shirts and 88 cent socks. Aldi grocery stores pay like 11 an hour to cashiers and you can still get 1.25 strawberries. I think companies as a whole fortune 500 and so could lower compensation for CEOs and board members and spread the income to employees and "eat" a raise in the minimum wage, but for some reason it isn't really fathomable to our society that happens, it's more they still make 25-30 million a year and for lower wages to make more we have to raise prices. I think that is a whole separate issue.
I meant the places you mentioned where you and your wife work that raised everyone's pay.
