What Trait Is Most Missing From Our Society?

I often hear people lamenting some trait that has gone missing from our society. If we want to go back to happier, more productive days (so the theory goes) we need to return a particular behavior to our national discourse.

For example, some say we need civility. Others might suggest we have a lack of honesty. Or respect, compromise, empathy, or even a willingness to listen.

Is there a particular trait or behavior that we seem to be missing? Which ones do you think are most important to a healthy society?
