I would start by saying a "human moment" I think of "people being people, reacting as ordinary people under pressure or to stimuli". By "squeeze human moment into ..." They mean captured(filmed) complex human moments and made it into a hollywood production. In other words he was able to capture moments of people reacting as people do to pressure or stimuli and turn it into something that people would want to watch. The last part "hollywood ready" means that it's not just a camera following around people. It's a proper full scale production with all the theatrical elements of a hollywood production, like creating suspense, foreshadowing, getting the right people on tv and edits etc etc. "What does "stripped away the tendency to privilege what some call identity politics" mean?" To understand this you need to understand the types of shows that Mark Burnett produced. I may have to think about this more, but I think the statement is referring to the people in the shows he produced. The way things were set-up by his narrative political alliances were broken (stripped away identity politics). In shows like "The Apprentice" or "Survivor", "Shark tank", people often have to form political alliance to survive, but they are often stripped away as everyone is fighting for themselves. that's my take anyway.

All these words have rich meanings. It would take a long time to explain and we would need to study the context.
