Yes, oddly compared to taxis my experience in the US with pedicabs is that they're almost all white men driving. More of a freewheeling low responsibility type of job rather than providing for a family type situation. I wonder what sort of social shift resulted in this?
If it's anything like the sport of bicycling in the USA, for a long time it's been a sport of caucasians, this is changing a bit but it trickles all the way up just from a sampling of who represents the USA at the Olympics and World Championships. Possibly a combination of the high cost of entry with the clique-ishness and the sport requiring quite a bit of free time and the support or money to have that much free time. Not talking about kids riding around the neighborhood but people who continue or start riding as adults, so not a social shift at all but existing demographics.
