Basically everybody is a thief?

I feel naive to trust anyone but my family and friends. It looks like everyone is trying to steal from each other. They steal other’s confidence, identity, opportunities, money, fame and fortune. I mean everyone is a thief? and they get turned on by each other because of stealing and they get married because they both are thief. who should I trust? the streets are flooded by thieves. there is no moral nor conscious what so ever in reality?
