Has society molded you not to trust easy?

I believe that this is a bubble that everyone has to eventually burst and I want to see how many people still live in this bubble, as time goes by it seems like the world has adjusted to being less trusting towards others, if I'm not mistaken I believe there was a point in time where people would take leaps of faith with people to start relationships, leave the front door unlocked, have guests over, invite people over, even just socialize more with strangers but it seems like now people have adjusted to not trusting anyone and live by that completely, just seeing someone walking up to you or even in your direction on has you on your Ps and Qs.
