I would qualify this by saying many want to be in
specific entertainment industries for the (potential) glamor and fame, and will sacrifice a lot to reach that goal. Many may have more
practical alternatives, but are driven by a goal. This is the land of opportunity, and many dream of taking a shot at the big-time while still young and attractive. That window of time closes fast.
The idea of possibly being the next Elvis or Madonna if you accept being boinked by a pig with money is hard to turn down for many.
One of the reasons the game dev industry has more abuse (mostly non-sexual) than other software endeavors is because games are seen as more fun or cool to work on, rather than say a sales proposal tracking CRUD system. (I'm happy making sales proposal tracking systems myself, although I admit I have dabbled in the pop music writing industry, and still dabble in neo-renascence tunes.)
My daughter found the clothing fashion industry is similar: high pressure because many want the job of designer and scrape and claw to get it. She changed careers after some nasty office skirmishes among competitors.
