Proposition 28 from this 2000 survey ([Fuller and Geide-stevenson 2010](https://www.tandfonline.com/doi/abs/10.1080/00220480309595230)) of American economists shows that 49% of American Economics Association members agree, and 31% agree with provisions, that it is a legitimate role for the government to redistribute wealth. 

That was an increase over 1990. 

Policy beliefs rely heavily on values, but is there substantial evidence showing that the policy of governmental redistribution improves either long-term economic growth or long-term absolute well-being of poor people?
