1.  The  noLon  of  equality  

•  Just  like  liberty,  freedom  and  democracy,  (most)  people  are  in  favour  of  equality  (of  some  sort).  

•  Equality  is  a  contested  concept  (cf.  liberty).  •  Equality  is  a  relaLonal  noLon  –  equality  between  whom?  

•  Also  need  to  specify  what  it  is  that  we  should  equalise.  Presumably  we  don’t  care  about  equality  between  people  in  all  things  –  then  you  get  idenLty.

1.  The  noLon  of  equality    

•  Equality  has  important  poliLcal  and  moral  connotaLons:  –  JusLce  as  equality  before  the  law  –  JusLce    as  democraLc  equality:  ‘neutrality’,  ‘anonymity’.  

•  Equality  also  has  important  connotaLons  for  distribuLonal  jusLce*.    Here  we  are  interested  in  economic  and  social  equality.  

•  ‘Why  equality?’  –  we  will  deal  with  this  quesLon  later.  

*  Although  we  could  argue  that  poliLcal  and  legal  ‘goods’  are  distribuLonal  in  nature  as  well.

1.  The  noLon  of  equality    

•  If  we  fix  the  ‘who’  quesLon  to  adult  members  of  a  given  state,  the  ‘equality  of  what?’  quesLon  has  a  number  of  possible  answers:  – Equality  of  welfare  – Equality  of  resources  – Equality  of  opportunity      

•  For  what  goods,  under  what  condiLons,  is  equality  jusLfied?    For  what  goods,  under  what  condiLons,  is  inequality  jusLfied?

1.  The  noLon  of  equality    

•  What  might  jusLfy  unequal  treatment:  – Property  rights  (Nozick)  – Disability  (Rawls)  – Desert  (Nozick)  – Efficiency  (Rawls)

2.  Equality  of  welfare  

•  PosiLve  freedom  is  about  how  many  doors  are  open  to  you.      •  NegaLve  freedom  is  about  whether  they  are  locked.    •  Both  posiLve  and  negaLve  freedom  are  about  the  acLons  

you  do/  can  take.  •  Your  welfare  is  enhanced  when  you  find  what  you  want  

behind  the  doors.

2.  Equality  of  welfare  

•  Welfare  is  the  saLsfacLon  of  preferences.  – When  you  get  the  state  of  the  world  that  you  want.  

– When  the  outcomes  are  in  line  with  your  desires.  

•  AlternaLvely,  welfare  is  a  hedonisLc  state.  •  If  we  are  asking  ‘equality  of  what?’,  then  surely  welfare  is  the  ‘what’  that  we  really  care  about.

2.  Equality  of  welfare  

1.  The  problem  of  offensive  tastes:  – Suppose  you  have  a  preference  for  something  other  people  find  distasteful  e.g.  harming  animals.    Why  should  others  help  you  saLsfy  such  preferences?

2.  Equality  of  welfare  

2.  The  problem  of  expensive  tastes  –  Suppose  a  father  is  wriLng  a  will  and  has  three  sons  who  may  inherit  his  goods.  

– Alan  has  culLvated  a  taste  for  expensive  wine  and  caviar.  

–  Brian  is  happy  with  beer  and  chips.  –  Carl  has  a  physical  disability  that  affects  his  mobility.  –  The  father  may  be  happy  to  give  more  money  to  Carl,  so  that  Carl  and  Brian  have  equality  of  welfare.  

–  But  why  should  the  father  give  more  money  to  Alan  rather  than  Brian?

Dworkin:  a  shipwreck  and  an  island  

•  Suppose  a  group  of  people  are  shipwrecked  on  an  island  with  abundant  resources.  

•  The  group  agree  that  antecedently  no  one  is  enLtled  to  any  parLcular  piece  of  property.  

•  Envy  test  –  no  division  of  resources  is  equal  if  any  immigrant  would  prefer  some  other  immigrant’s  bundle  of  resources  to  his  own.  

•  A  single  agent  would  not  be  able  to  divide  up  the  resources  adequately:  –  A  milking  cow  cannot  be  divided  –  Some  combinaLons  of  goods  in  bundles  suit  some  rather  than  others

3.  Equality  of  resources  

Page 19: Part 1B - Political Philosophy - Equality - Lecture 1 ... · Part 1B Paper 7: Political Philosophy / Equality Lecture 1: Equality of What?! ChrisThompson cjt68@cam.ac.uk! 1

An  aucLon  

•  The  soluLon  is  to  have  an  aucLon.  •  Everyone  gets  the  same  number  of  tokens  (clam  shells).    

This  serves  as  a  metric  for  equality  of  resources.  •  Every  item  (land,  milking  cows…)  is  put  up  for  aucLon.  •  Bidders  can  ask  that  any  porLon  of  a  good  (e.g.  a  

subdivision  of  land)  be  placed  separately  on  the  aucLon.  •  The  lots  are  then  sold  to  the  highest  bidder.  •  The  envy  test  will  be  met.    No  one  would  prefer  to  have  

someone  else’s  bundle,  because  by  hypothesis  they  had  the  opportunity  to  buy  it.    

•  No  one  will  be  unhappy  with  the  make-­‐up  of  their  bundle,  because  they  added  items  to  it  themselves.

3.  Equality  of  resources  

Page 20: Part 1B - Political Philosophy - Equality - Lecture 1 ... · Part 1B Paper 7: Political Philosophy / Equality Lecture 1: Equality of What?! ChrisThompson cjt68@cam.ac.uk! 1

Equality  of  resources  vs.  welfare  

•  Someone  can  sLll  think  themselves  unlucky:  –  The  island  does  not  grow  the  fruits  they  like.  – A  lot  of  people  share  the  same  tastes  and  so  the  bidding  is  intense  

•  But  these  concerns  relate  to  equality  of  welfare.      •  Under  equality  of  resources  people  must  make  choices  in  light  of  scarcity.      

•  It  is  OK  if  our  choices  impact  on  others  (we  outbid  them);  we  are  not  acLng  unjustly,  since  equality  has  already  been  established.

Inequality  again…  

•  Arer  the  aucLon  has  concluded,  people  can  then  get  on  with  their  lives,  produce  things,  and  trade.      

•  The  iniLal  equal  distribuLon  of  resources  will  quickly  be  disrupted:  –  Some  are  more  skilled  producers  than  others.  –  Some  work  harder  than  others.  –  Some  will  get  sick.    Some  will  have  their  crops  destroyed.  

•  Before  too  long  the  envy  test  will  no  longer  hold.    As  such,  we  no  longer  have  equality  of  resources.

Page 22: Part 1B - Political Philosophy - Equality - Lecture 1 ... · Part 1B Paper 7: Political Philosophy / Equality Lecture 1: Equality of What?! ChrisThompson cjt68@cam.ac.uk! 1

Luck  

•  OpLon  luck  –  the  result  of  how  deliberate  choices  pan  out.  E.g.  Which  crop  to  plant.  

•  Brute  luck  –  the  result  of  risks  that  you  do  not  deliberaLvely  choose.    E.g.  The  weather.

Page 23: Part 1B - Political Philosophy - Equality - Lecture 1 ... · Part 1B Paper 7: Political Philosophy / Equality Lecture 1: Equality of What?! ChrisThompson cjt68@cam.ac.uk! 1

Luck  

•  It  seems  fair  to  hold  people  responsible  for  opLon  luck,  but  what  about  brute  luck?    If  one  farmer  plants  a  crop  that  survives  the  storm,  whereas  another  farmer’s  crop  is  ruined,  is  the  inequality  in  resources  just?

Luck  

•  It  seems  fair  to  hold  people  responsible  for  opLon  luck,  but  what  about  brute  luck?    If  one  farmer  plants  a  crop  that  survives  the  storm,  whereas  another  farmer’s  crop  is  ruined,  is  the  inequality  in  resources  just?  

•  Insurance  provides  a  link  between  opLon  and  brute  luck.    E.g.  farmers  have  the  opLon  of  purchasing  insurance  against  adverse  weather  events.  

•  We  can  suppose,  for  example,  that  sighted  people  can  choose  to  purchase  accident  insurance  during  the  iniLal  aucLon.    No  need  to  redistribute.

DisabiliLes  

•  But  what  about  disabiliLes?    You  can’t  buy  insurance  against  pre-­‐exisLng  condiLons.

DisabiliLes  

•  But  what  about  disabiliLes?    You  can’t  buy  insurance  against  pre-­‐exisLng  condiLons.  

•  HypotheLcal  insurance  market.    Determine  how  much  people  would  be  prepared  to  pay  for  insurance  against  various  condiLons.    Fund  the  equivalent  of  this  insurance  via  taxaLon.

A  lack  of  talent  

•  But  what  about  those  born  with  a  lack  of  talent?

A  lack  of  talent  

•  But  what  about  those  born  with  a  lack  of  talent?  •  This  is  trickier.  •  It  is  difficult  to  be  precise  about  how  much  a  lack  of  talent  might  be  a  disadvantage.  

•  A  hypotheLcal  insurance  market  against  the  risk  of  not  being  a  superstar  would  offer  insurance  that  is  bad  value.  

•  A  hypotheLcal  insurance  market  might  produce  good  value  products  against  being  very  disadvantaged.    A  minimum  income  guarantee?

Summary  

•  So  how  does  equality  of  resources  (ala  Dworkin)  fare?  

•  The  major  problem  with  equality  of  welfare  is  people  culLvaLng  expensive  tastes.  – The  aucLon  holds  people  responsible  for  their  preference  formaLon.  

– The  hypotheLcal  insurance  markets  place  an  upper  limit  on  the  amount  of  compensaLon  due  to  people  with  disabiliLes  or  a  lack  of  talent.
