This reminds of a trend I read about a while back where the rewards accrue to an increasingly small number of high profile people in a field while the majority just get poorer.
Malcom Gladwell had written about it, how most gangsters, Sumo fighters are poor. It can also be observed in other industries like art, sports, music. In India till some years back it was difficult to get food money in these industry. With rising income and middle class some sources like local events and training to kids have come up, but still these career options are seen as a high risks.
