i did a study and an interview series on these questions - between 2006 and 2009 - you can find all infos on http://www.kanonmedia.com/portfolio/voices.htm
, some of the interviews are in English, the study is in German only, we did not have enough resources to translate it, the main result is that most of the artists cannot live from their art production and that creative industries is no solution to this question as they - as the word industries indicates - are embedded in commercial, i.e. applied businesses, in a high number of cases service-oriented. The idea of improving the situation of the arts by changing the approaches and goals, thus identities of art production more and more into the profile of the creative industries is a neoliberal idea coming from the 90ies. one could say that about all ec-studies prove that economically it does not work. but one can also notice that through such approaches the arts have been turning more and more into a theme and event business where artists loose more and more the freedom and choice to choose what they are striving for to work on but still are the loosers of the game.
