What does it mean to be socialized, not in a fiscal manner, but in a cultural manner?

I was listening to a portion of a public radio program the other day and this thought crossed my mind.

What does it mean to be able to function in society? Does it mean that we’ve been socialized to act a certain way? Does being socialized mean that other members of society can expect us to act a certain way, without their saying so? What has to happen for a person to be socialized in a cultural manner? Are some people born with the ability to optimize their participation and success in society without any outside guidance? Does every person need to be programmed to function in society and how does this happen? What are your thoughts?
