how is welfare distributed

One of the essential debating points in modern voting systems is how welfare should be distributed. Welfare distribution is the perfect topic for politicians to debate about. We would like to know which mechanisms make individual people and society more rich or less rich? What determines the welfare distribution? We have found (an incomplete) number of factors affecting welfare distribution:

– self enforcing of inequality: the paper and internet article.

– rents increases the gap, the  video starts in icelandic but continues in english after 1 minute and explains how this works: video 1 and video 2

– science  decreases the welfare gap by new inventions that enable (poor en wealthy) people to do more with the same resources. Do you have more factors? Send them to us by submitting a paper!
