mansion ji, When we talk about "socio-economic structure"; psychological conditions are already shaped by the social structures too. Again, it can be argued that pyschological condition is intrinsically an internal locus of control or internal, or infact both. Ceteris paribus, the shades of gray are infinite. There are as many catgegories of people as the number of people themselves (itself?). So, even if you choose to "control your mentality , perception," or " not to" you belong to a catergory of your own. And as I told in my earlier thread, he is not an "indifferent" reader, please refer his other posts and you will understand. With respect, meek_misfit
