IOW, I don't believe that middle class Americans are turning to dumpster diving.
I was ‘upper’ middle class and I was in a position that I had to do it.
It saved my life!
I live in middle class America and three days ago the largest city around here which is about 50K population- made it illegal to dumpster dive. Methinks you might want to step out of your comfort zone and see what is going on in our country.
