In reference to those low-paying retail jobs: I have done some research on large US retailers like J.C. Penney, Gamestop, Macy's, Sears and Tailored Brands. It's quite scary to see how dire the situation is for these firms. Shrinking revenues, plenty of debt, hardly any profit in sight.
The most shocking to is the number of people they employ (more than 90k in the case of J.C. Penney), many of whom can be sure to be laid off in the next few years.
