"Most people are basically good" is untrue but useful; over ninety-five percent of the people you interact with aren't much minded to do you any harm and nearly all of the remaining five percent are in no position to do so.
It's not really because they are nice or good -- it's because it's easier to get along than not, easier to smile and nod than clonk you over the head with a club and try to evade the consequences.
You are surrounded by dangerous primates, the single most deadly species on the planet, proven killers; and you're safe because for nearly all of them, harming you is simply too much bother. You're in far more danger, orders of magnitude more danger, from the things they do carelessly than any deliberate act.
Smile, nod, be friendly. Being pleasant will make your own life more pleasant; but do remember, those creatures are dangerous.
