Somebody was having a bad day:
It's difficult to read but the bottom image says "Change = Rich" then "Homeless" and "New target demographic". Somebody was feeling a bit cynical about their happy shiny job... hmm? I find bizarre images and messages like this all the time. It's usually one of the artists. They often feel repressed and I think this is their way of branching, well really lashing, out. I try not to judge. We all have those days.
