To me it is just another indicator of how broken American society is. A fast food place serving terrible and unhealthy food is becoming a gathering place for poor people who are probably the ones most in need of a healthier and better lifestyle.
It is also a sad reminder of how society has gone so utterly wrong when the cheapest food is the absolutely worst food.
This is of course not McDonalds fault, but society has allowed huge chains pushing cheap unhealthy food to the masses flourish. It isn't just about the food, but the sort of cultural wasteland a place like McDonalds is. Everything mass produced and equal everywhere. A country priding itself in diversity is drowning in homogeneity.
