I live in a pretty typical American middle class neighborhood far from any tech centers and Airbnb is almost universally hated around here, for pretty much the usual reasons you hear (disruptive guests, housing availability, etc). Airbnb clientele is heavily skewed towards techies and upper-middle class in my experience. Folks traveling on a limited budget either can't afford Airbnb or can't spare the extra time they take compared to a hotel.
