Bottom Man

Okay, let's assume that the racial totem pole goes - White>Hispanic>Asian>Black>Native American>Other (Or something like that.).

Who is really the bottom man or woman?
Is it the obese?

Could it be those in the the GLBT community?

Or someone who is handicapped?

Or homeless?

Or poor?

Or mentally retarded?

Or the ugly?

Or is it a combination of these factors in addition to race?
