Describe symbolism in The Little Foxes by Lillian Hellman

The symbolism in this play about the greed and revenge that destroys the Hubbard family and everyone associated with them is subtle but effective. Oscar, the least clever of the three siblings, enjoys his daily sport of hunting wastefully discarding his bounty. He completely monopolizes the local hunting area, thus denying the black population much-needed access to meat. His pastime has symbolic resonances to the "hobby" he and his siblings make of their struggle for power and wealth, both endeavors involve killing for the sheer pleasure of killing and a drive to dominate others and monopolize resources beyond what is needed.
