The question should be, I think, what causes secure attachment? Largely, it seems to be a lack of anything bad happening. Care providers are there to meet needs, provide comfort and generally, one would imagine, to provide care. But if a person is in a situation where all their needs are generally met, they feel secure, it's likely an environmental aspect. Their family has sufficient money, good health care, supportive, or they are in some kind of environment that inhibits negative influences.
But if the child grows in a similar environment (and most people never go too far away from where they were brought up), their later lives will be influenced in the same way - minimizing negative influences such as disease, financial ruin, and despair.
And it would be easy to imagine such a person would have a generally good sense of well-being.
Perhaps? I have no science to support any of this, and am therefore reluctant to put it out there. But there it is.
You may have a point. A secure upbringing less any significant difficulties may yield a secure adult. Your idea about an adult benefitting from the same situation he grew up in would also help him be more secure and socially attractive if he does remain close to his parents and home.
Your comments, though, bring a question to mind: I have yet to meet someone who has not endured some kind struggle. I admit that struggle is relative, and that some have to endure much more dramatic pain than others, but don't you think that everyone has suffered? If they haven't, your idea may hold true. If they have, how do you think that plays into your thoughts?
