Concern has been expressed that the new generation of artists (musicians, actors etc.) in the UK seem to primarily come from upper middle class backgrounds[0]. I have started to wonder if the same could be said of the tech startup scene, e.g. in London. This could be due to the increasing difficulties someone would have living on a period of effectively zero income, unless they had the backing of rich parents.
