CASTE  !  CASTE  !!   AND   CASTE  !!!
 ( And  it's   Root.)
==============================
In olden   ' Pre-Axial  Civilization ' certain   occupational  practices  were    carried   by  certain   particular  family  for  generations  together ( Examine  the  Science  of  ' Division of  Labor) '.)
In  those days  Brahmins   were   only    learning and  guiding Society  with  Religious  and Spiritual  practices  in  life .
 To  me,   a  Mr . Chakraborty     working   in  a  BANK  or   owning  a   Cloth -shop  has  no  right  to  claim  to  be   Brahmin . Conversely  Naren  Datta  ( Swami  Vivekananda )  though  a  'Kayastha   sub-caste '  was  more 'Brahmin '  than  any  Brahmin  of  any  name  or  fane , I know  of  .
Let  me  deal  with   USA  for  better  interpretation :
EINSTEIN   was   a  BRAHMIN   of  highest  order  as   he   Expounded  all  mysteries  of  RELATIVITY.
USA -GENERAL   is   a  KSATRYA ( whatever   is  his  DNA- Root).
D.  Trump , I  think   is  a VASHYA  ( Commercial Class )  and  on the  TOP  by  his  Talent .
And   if  a professor's 's   son    works  in  PATH  MARK -  SALE  COUNTER (for  example )  he  is  only  a   'Sudra'  like  me .  Read  Ravi  Batra 's  book (  of  USA,   for  more  about  it ).

It  is  QUALITY  of  attainment  that  decide  the  CASTE   AND  NOT  MERE  INHERITANCE .
(  It  is  none  of  my  ORIGINALITY; but  was  scripted atleat  1500  years  B.C  in   The  GEETA (Indian  Vedant-ic Exposition  : Ch : 18  , Sl. 41)..
CASTE  IS  A  QUALITATIVE   CLASSIFICATION   AND   NOT  ANY   POLITICAL   MEANS  OR   'WEAPON "
