$600-$700 million net worth? Fat chance. I would believe that Carlo was in the neighborhood of $50 million "net worth" as his sons inherited most of his fortune. Remember, if the Gambino's were grossing $500 million per year, they had to make obscene playoffs to politicians, judges, cops, councilmen, selectmen, union officials etc. Their "net profit" or take home was in the ballpark of $50-$100 million per year which had to be whacked up amongst the administration, Capos, made soldiers etc.
