What about the relative richness? If you are born in some poor country (better if not in a war) and earn 2k USD a month, you would be considered rich in that country. Living on 2k USD in Switzerland/Singapore/main cities (San Francisco, etc.) is below the poverty line. Does this account for such distinction? Having experienced different countries, I would rather live with 2k USD in a third world country rather than 2k USD in Singapore.
