I couldn't but wonder how everything we see or hear affects us all as people. The very many negative news cycle (crime, economy, social issues) is a big repertoire for ideas for writers. Same could be said of positive news cycle. But also, could it be that some readers read something (new) in a novel and wanted to act it out or lead to a major movie or TV series? Is it selfish of an author to want to say exploit..the kidnapping and the returning of a woman for an epic crime novel? Would it be selfish to make an unwanted character that won an election against all odds for a political drama? just to name a few real life situations I would say we all feed off of one another.
