You can see this in action almost every day in New York City. On a crowded subway car, if a pregnant woman or very old person gets on the car it is almost always a Hispanic male who jumps up to offer their seat, even if it means standing up for the rest of a long commute.

As a middle aged person who grew up in Houston, I can remember having these basic values (golden rule/help other people) drilled into me by parents/teachers in the 70's.

Somewhere along the way urban life seems to have washed those values away.
