If you mean keeping around people who have many flaws for improvement, probably. I tend to be drawn to people with inner conflict. It seems I have an urge to try and fix it. It's like an unsettlement in my environment that is constantly prodding at me.
So people who need some sort of help... yeah I keep them around. I don't like the prospect of leaving someone defenseless or vulnerable to future damage.
If you mean social status and class however, that sort of thing doesn't matter to me. I'm not one to descriminate on lower education nor do I put value in material possesions. I value a person for the person themselves and not their outward appearance unless of course it defines them in some way. The amount of money they have or the amount of connections or friends they have may give some indication of who the person is but it doesn't display the whole picture. If I deem that person is someone I'd like the company of, then I will seek it and keep it.
